Gday guys, Yet again I find myself asking the gurus for guidance, I think I have killed my un killable 1uzfe engine, The other morning i floored the bugger to get around a semi, once I was out and about she lost power and started to jerk and jolt, right down on power, then once i had pulled into the driveway I got the jap dash warning "Engine electrical warning" and it now runs, but wont rev over 4000rpm and its like a volkswagon, kind of like the old falcons engines when the points were knackered, they ran rough as guts... I have got the usual stuffed fuel ecu problem,I diagnosed that this morning with the bridge in the diagnostic port,(thanks to the forum) could this be the problem? (It didnt fix the rough revving when bridged though) The other thing im concerned about is possibly that the engine ecu has decided to give up, but i dont know if they completely die when they go or give warning...any suggestions? as usual when it comes to these cars I am stumped...Hope someone can give me an idea where to start...
cheers

Possibly an ecu issue, also most likely that one of the coils has died. |

That sounds less scary and less expensive than a new ecu, I will have a search and see if there is a tute on how to get at it to replace... Thanks for the answers, much appreciated 
One more question, are the coils easy to find to replace them? as in are they a repco or auto one part or toyota only?

Top coil is a 3 minute job, the one near the AC pump is a bitch. |

Is one more prone to fail than the other Rob or is it better to just replace both? |

A/C one is easy if you left out the front mount bolt when you changed the timing belt/waterpump. 
Neither is more prone, but I would replace both, and then keep the good one as a spare in case you ever need it.
Coil is common to some camry's and other cars, so easy to get. Can get Toyota ones or Champion part no CC231 (check this number first) is available from any good parts store. |

Ok I disconnected the coils one at a time, it seems they are not the problem, im now thinking breaking down leads and dead plugs perhaps, the car idles like there is nothing wrong, it accelerates fine when you dont give it a lot of pedal, its only when the car is under load and trying to get up a bit that is slower and rougher than a geriatric goat, fingers crossed that is it, just need to find the plugs and leads now so off I go to search for part numbers...Somedays I think I would have been better off staying with the fords...thats just stupid thinking right there!! |

Well I changed the ignition leads thinking that was the problem, did nothing. The plugs are all about 3mths old so they are good..Its still running like its on 4 cylinders! I Have found a fuel ecu on ebay, should have that by weeks end if i win it, im wondering if my problem is the main ECU? Do they break down and affect engine power or just totally die when they go? I seriously dont know what else to check! Looks like its off to the mechanics for a diagnosis check...even my Brother in law who is a toyota factory trained mechanic is scratching his head as to what the problem is...Im Starting to dislike Soarers lol |

bridge the F1 & B+ ports in your diagnosis plug and it should stop stalling as this bypasses the fuel pump ecu. |

Scott;
Coils tend to break down under load mate.
i have found that if the top coil goes(the one you see when the bonnet is opened) the car will not fire.
If the other one (just above the air con pump)it will be able to fire but run on 4 cylinders.
the only way to sort it out properly is put it on a dyno mate and load it up if the mechanic is any good he will pick it up pretty quickly
also make sure your air flow meter is plugged in properly and working. This will also give the same error code you have and cause the car to die like what you have explained above |

Thanks again everyone. Jan I did the bridge from F1 to B+ I need a new fuel pump ecu hehe...It still runs rough when bridged though.
Lew Thanks for your input, I checked the coils, not with any specialised equipment but they gave me a nice shock (insert rolls eyes emoticon) so I assumed they were ok, so what you are saying is they can still crank out spark at idle but break down under load?
I was told to bridge TE1 to E1 and the error codes I got was efi N/G (im guessing Fuel ecu) and had an ECT N/G, (??) thats all I can get,Im told there are number codes, but i dont know how to get them to work,My brother told me to bridge another 2 to make the check engine light blink the codes but that didnt work (no check engine light)I will take it to the mechanic and get him to plug into it to see whats what..Oh to go back to a day when an engine was simple and you could diagnose it yourself... |

Aaaaargh, clean the points with sandpaper and twist the distributor cap until she runs about right. 
Meanwhile, I'll drive my modern Toyexus thanks.  |

Haha yeah thats about right David...Tweak the dizzy, adjust the fuel/air screw on the carb and adjust the points just right and away you went... I am not enjoying the niggley problems I'm getting from this car but I can safely say im still hooked on them. I guess what im experiencing is the results of previous owners inaction and neglect..Should be a good car once I have thrown bucketloads of cash at it to restore it to what it once was. |

I replaced both coils today...and lucky me...its still doing the same thing... so far $400 replacing bits that dont need fixing...SO glad I bought a money pit. 
Lew is there any way to determine how the Air flow module thingamajig is working or not?

Borrow one and test it.
Could also be crank angle sensor or cam angle sensor.
It's rare, but not un-heard of that the cam belt could have skipped a tooth, which will do a similar thing.
Sorry for the guess work, but it can be difficult to try and diagnose a problem over the internet. |

Thats cool Dan, My Brother in law suggested a crank angle sender too when i rang him before but also thought it would be rare, sucks that im so far from everyone here...At least the positives are it now has new leads and coils
Will limp it to the mechanics tomorrow for a plug in to try and diagnose its problem |

Scott Craig won't have one mate he has a celsior and thay are different to the soarer ones.
The closest person i can think of that might have one would be Mr Hayden and he would be able to help out a little more with information
I think he is away with work about now. |

Thanks Lew. I bailed Craig up at the Supermarket and he teased me for having a Slow model Soarer! Elite bunch those TT owners haha... The Mechanic has had the car a few days now and he thinks it is dizzy problems, im guessing by the fact that repco and other spares stores dont have listings that Toyota have restricted these as toyota or lexus only parts? Been quoted $73 each cap from the local dealer, im hoping i can find them a bit cheaper somewhere. |

Scott call me mate you are being torn a new arse hole. 0400 834329
Bursons have the dizzy caps LS400 are the same beast.
there are a few more things that can cause dramas as well. |

Appreciated you taking the time to offer phone advice Lew. I couldnt believe Bursons would want more than Toyota for caps..turns out the dizzy caps are good,no cracks but both rotor buttons are broken on the tops as well as badly cracked everywhere else, im guessing they are as old as the car... Waiting for good old Toyota to get them in on Thursday,as no one else sells them or they are more expensive than Toyota(Again Bursons, go figure). So the fun continues...What an expensive learning curve this is becoming...
Funny how people hear Lexus V8 and instantly assume you want to pay more and can afford to. |

It wasnt the rotor buttons either
Apparently the cam angle sensors are ok.
Ran crap when cold but it actually runs better and once it is warm its running at 80% but still have the miss and the jap warning up.
Next avenue...ECU... are they expensive?? Does anyone have one available at a reasonable price for sale?
Failing this I will sell it for parts. |

Wouldnt have thought I would be getting the electrical warning if it was that dire...
That would involve another stint at my mechanics and after it took him a week and $300 to change rotor buttons im not keen there
I SO dont want to be thinking about that until I have ruled out the ECU.
Watch this space :/ |

Ive tried a UZ32 ECU,wasnt the problem
At least i now know mine is fine as it still has a miss, although since ive replaced the rotor buttons its running better...Im at a loss what it is,Its gotta be something minor but i just cant find it...could be the plugs,havent changed them cos i was told they are ok.. im stuffed if i know what it is. Wifes told me to sell it, cant spend anymore on it so if anyones looking for a cheap Limited its in the cars for sale section |

Maybe get a 2nd opinion on the plugs Scott. Might be something the mechanic missed like a hairline crack or the like. |

Ive pulled the covers off, the dizzy caps have about 2mm of carbon on the contacts... Great to know i pay a mechanic who fixes one thing only to "troubleshoot some more" ($$$) once its all back together again.
I have found chewed up cam angle sensor harness, it has come free and rubbed on the serpentine belt and it has gone through the protective cover and broken some of the insulating wire around the red and white wires, I joined them back together and taped it back up but it has made no difference, Im guessing a replacement sensor is needed....Now to find one of them... |

Changed both cam angle sensors... STILL rooted!!
Been searching the net and have discovered code 13 means the cam belt has jumped a tooth..that is all there is left that I haven't done...probably the one thing I didnt want to have to fix. Putting the car into another mechanic to get the timing belt and bearings replaced...engine has done 270k so it was going to be needed in 30thousand k's anyway...hopefully that will rectify the problem and give us another 100k. I have been so tempted to sell it for a parts car and be rid of it...but I refuse to let it beat me!!! |

That's the way to go with this beautiful car. I have heard that you don't need to change the timing belt after 100k with the new belt, they say 170k, I don't know if its true or not. But if that all what is happening with a worn belt just drive till it's "rooted". Hang in there.
I also refuse to get rid of my car, I have spent ~$92000 on repair and upgrades during 10.5 years now. |

Update...Its dead! Took it up to melbourne this morning, it ran well, on the way home I made it back to Lang Lang and it died...lost power totally. I opened the bonnet, but being dark I couldnt see anything except the engine looked covered in water...I thought it had maybe done a water hose. Left it for a few minutes then tried to start it again and my jap fault code is back "engine electrical problem". Gave it a decent rev to see if it cleared up and then noticed the grass underneath had started to catch fire, looked underneath and the whole exhaust system was glowing red! I guess I have burnt out the cats... but does that cause a almost total engine power failure and fault code?
When I get it back home, provided it hasnt been vandalised, burnt or stolen Im selling it for parts...Ive had it...Nothing worse than trying to hitch hike to Phillip Island from Lang Lang in the dark when no one will stop to give me a lift.... |

Ok Scott,
guess what my 32 just pulled up your problem..
have you noted, will run fine then be hard to start warm. Once you get it going it runs ok until you encounter the dodgy start again... I sarted running through the usuals.
Being a bullet proof Soarer, think outside the soarer matey.... a dose of shitty fuel thats left water in your system (or slight chance of pump failure, blocked fuel filter from the shitty fuel n possibly even blocked injector/s). I was gonna bridge fuel pump ecu(as per klingon interpretation)
BP is apparently the culprit, I bought premium unleaded as usual....then klingon...translating to electrical...however I think the octane level is too low, and conning the ecu (some dud reports) into asking shitloads from drivers wallet!! Don't let the buggers con you...lol.
OK the fix is.
1. drain tank new fuel filter.
2. There is an additive (???), that fixes it without step 1.
3. get it running, jerry in boot, run dry/real low, then retop up.
I first added octane booster, then added more juice....mistake!!!! Although it did run ok again immediately, it returned.
So back to step 2. (if i'm lazy), or step 1. (the right way). |

Well the Cam belt idler bearing decided to seize and shredded the cam belt. It actually jumped 4 teeth!! Its in now stripped down to its underpants awaiting a delivery of a new belt, water pump (which Im told was very close to death) new idler bearings, tensioners etc.
We had the conundrum of selling it, only to buy a car with probably more problems, or spend the grand to fix it, we have decided to stick with the devil we know..
Hopefully it will be fixed late monday and back purring like a new car
Im going grey with all these dramas haha! |

You'll be right mate. Glad you found the problem.
Bonus is, once this is done, all the work for the 100k service is done and you should be able to enjoy for a while wit just basic servicing. |
