Bump.
Ok I just cleaned the AAC valve, and reset the idle with the TPS disconnected and using consult with ECUtalk to get exact RPM.
After setting the idle RPM I then rigged up the timing light and checked the ignition timing which was reading 12deg @ 650. So I advanced it slightly by adjusting the CAS until it read exactly 15deg @650 with the TPS disconnected, according to the marks on the pully wheel.
Once I reconnected the TPS it read the same thing, 15 @ 650. And It also read the same on ECUtalk timing read out, so all seems good.
Took it for a test and it ran well, except for the fact that this one thing that was happening before the 100k km service, is still hapenning;
Once it's warm, when I first click it in to gear and the engine is first under load the idle drops right down like it's about to stall. It has a bit of a cough for a second and then pics up and I take off, and it doesn't happen again?
Any ideas?
Injectors? (but doesn't seem to happen any other time through the rev range)
Coil packs failing?
What do you think?
