Hello, I have repaired higher than 30000 vehicles in my career and I dependence to ask you questions in the past I am not there in person to hoard facts, data, or to exam your vehicle. I may question you to undertaking scrutiny in my stead. If psychoanalysis is needed and you would rather not take effect testing, I can allow my best advice, Fuel pressure?
Its also worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will every consequences in insufficient fuel visceral delivered to the engine. Might in addition to be worth cleaning out the idle quickness govern motor / valve as these acquire clogged taking place past carbon and some brake cleaner washed through helps release things off.
I don't have any check engine lights unless I unplug the MAF sensor. when the MAF is plugged in after that the car will stall unless I put my foot on the accelerator. There is in addition to an intermittent popping sealed coming at idle.
