i think ive tried everything folks and to no avail
my summer project is still kicking my butt
i have replaced cats, ecu's, maf's and vacum hoses
and i still have the same issue of the damn thing will not rev past 4k and is kicking black smoke from running extremely rich, i just have a few final questions before i totally give up , as this project has me to the point where i am doubting myself and what little mechanical skill i thought i had gained.
1 can the idle air control valve be completely removed without harming functionality of the motor?
2 if the fuel return line is too large would that cause a rich condition in the engine
3 what would cause the maf and iacv to not communicate with the ecu?
im officially stumped with this project daily driver please anyone, i really need a direction to go in
thanks
