Hello, I have repaired over 30000 vehicles in my career and I craving to question you questions previously I am not there in person to stockpile facts, data, or to exam your vehicle. I may question you to achievement examination in my stead. If examination is needed and you would rather not action testing, I can allow my best advice, Fuel pressure?
Its furthermore worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a below par pump will all upshot in insufficient fuel subconscious delivered to the engine. Might moreover be worth cleaning out the idle quickness control motor / valve as these get clogged up taking into account carbon and some brake cleaner washed through helps clear things off.
I don't have any check engine lights unless I unplug the MAF sensor. subsequent to the MAF is plugged in after that the car will stall unless I put my foot upon the accelerator. There is in addition to an intermittent popping unquestionable coming at idle.
