Hello, I have repaired on top of 30000 vehicles in my career and I dependence to ask you questions before I am not there in person to hoard facts, data, or to exam your vehicle. I may question you to do something psychotherapy in my stead. If chemical analysis is needed and you would rather not perform testing, I can manage to pay for my best advice, Fuel pressure?
Its along with worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a in poor health pump will all consequences in insufficient fuel being delivered to the engine. Might then be worth cleaning out the idle rapidity run motor / valve as these acquire clogged up bearing in mind 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. taking into consideration the MAF is plugged in next the car will stall unless I put my foot on the accelerator. There is afterward an intermittent popping sealed coming at idle.
