Hi Guys !
Thanks for your time for reading this.
I've been stuck on a problem lately as my GTV misfires under overrrun (at arround 2200 RPM and below )
Its more pronounced when it's cold..
My Car is 1997 PHASE 1 3.0 v6 24v ( with throttle cable )
I've got a lot fixed already, but I mighty be missing something, what I've done:
- Changed MAF
- Checked timing ( replaced whole cam belt)
- Changed Lambda (O2 Sensor)
- Checked spark plugs
- Replaced all inlet gaskets
- Checked for vacuum leaks ( replaced all bad hoses )
Could this be due to messing with the idle screw on the throttle body? The previous owner screwed it wide open so it wouldn't die because the MAF was faulty.
I have no clue what else this could be...
Do you guys have any clue? Please help this fellow out !
One more note, when its misfiring ( popping out of the exhaust, when I try to give it some gas, it will hesitate )
