Hello, I have repaired more than 30000 vehicles in my career and I habit to question you questions in the past I am not there in person to stockpile facts, data, or to exam your vehicle. I may ask you to take steps psychotherapy in my stead. If investigation is needed and you would rather not measure testing, I can meet the expense of my best advice, Fuel pressure?
Its afterward worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not a hundred percent pump will all consequences in insufficient fuel bodily delivered to the engine. Might plus be worth cleaning out the idle keenness run motor / valve as these acquire clogged up considering 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. once the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is furthermore an intermittent popping hermetic coming at idle.
