Hi all,
Just a follow up on what happened to my UZZ30. As mentioned in the other thread (1UZ sounding like a WRX), my V8 was running extremelly rough. In fact it too sounded like it was a WRX. It was idling extremely rough and rich. It was running so rich, I had pure fuel spitting out of the Left Bank exhaust, with a nice puddle to leave behind.
I took the car to Toyota to have it checked out (Big mistake, as they started with the most expensive repairs and used process of elimination, I had a few harsh words and they they stopped trying to screw me financially). Initially they informed me that it was running on 6 cylinders as 2 of the injectors were kept open. They believed the injectors were in need of a service and assured me that a good service SHOULD resolve the problem. Well, I had my doubts, as it was weird that two of the injectors would have gone cactus at the one time, and I assumed it would have been the ECU that was faulty.
Anyway, I took their word for it (Big Mistake # 2) and had the injectors serviced. When they put them back in, the problem did not go away, and THEN they said to me that it was the ECU... well, F***!!!!!
A new ECU from Japan was quoted to be $2,000, and I nearly fell off my chair. I asked if it can be repaired, and "supposedly" no one in Adelaide repairs them. (I found that hard to believe, so I contacted another well trusted Mechanic from Grove Auto) and he informed me of 2 workshops in Adelaide that do repair the ECU's. After many phone calls and a lot of running around, I had the ECU repaired at Automotive Service Solutions (they only deal with Trade, not general public). They informed me that there was a damaged (not sure if burnt out) Injector driver or something (maybe a capacitor) that needed replacing and a couple of other little faults.
Once I got the ECU back (only took them 1 day to do), I went back to Toyota to refit. I collected the car this morning and it drove like it used to (but we'll see over time as knowing my luck it will break down).
There was a lot of White smoke from the exhaust initially due to the unburnt fuel in the cat-converter, which was disappearing over time.
At this stage, the problem seems to have been resolved all due to the ECU having a fault.
I thought this may be of some use to others in identifying some of their car issues.

Thanks for the feedback and support guys.
Peter from Grove Auto was very helpful and so was Dino from Automotive Service Solutions. Dino mentioned that there was quite a bit of work involved and he charged me a total of $260 for the repairs, which includes GST, Testing and Quote for repairs, with a 12mth warranty. I am very pleased

Yes you do Mark. The reason why I opted for the above was simply due to location as it was cheaper to transport here. It also reduced the time taken to post/courier the ECU over.
Mark has also been a great help as he did mention that he has seen a few ECU's visit him with this problem.
