Hey guys,
Long time reader, first time poster. I have searched for hours without success..
The car in question uzz30 1992 JDM soarer converted to manual, standard ECU
The problem, after getting the two mid mufflers removed, the engine has been playing up, I can only compare it to what boost cut feels like, real violent, head banging hesitation. After weeks of fault finding with no results I decided to download the toyota car tester, wired it up and found I was getting 55 degrees ignition timing.. when I unplug the airflow meter the ignition timing is steady on 30, both idle at 10 degrees. I confirmed this finding with a timing light.
I opened the ECU, replaced one leaking capacitor, however no fix.
I am now wondering if the welding damaged the ECU in some way or a sensor is bad? I cant find any ECUs to test unfortunately.
Any help would be greatly appreciated
Cheers
Jason
