Hello, I have repaired exceeding 30000 vehicles in my career and I dependence to ask you questions before I am not there in person to accumulate facts, data, or to test your vehicle. I may question you to doing breakdown in my stead. If chemical analysis is needed and you would rather not fake testing, I can present my best advice, Fuel pressure?
I started the car going on this morning, it starts in the works and runs at 1750 and within a minute or for that reason climbs more than 2500.. It is dispensation mild though, just exaggeration far along than it should be. I next checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it support to exactly where it was. No vacuum leak sounds and all associates verified. I atmosphere good practically them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. once the MAF is plugged in subsequently the car will stall unless I put my foot upon the accelerator. There is next an intermittent popping hermetic coming at idle.
