Hello, I have repaired over 30000 vehicles in my career and I need to question you questions in the past I am not there in person to accrue facts, data, or to exam your vehicle. I may ask you to feign psychiatry in my stead. If investigation is needed and you would rather not acquit yourself testing, I can have the funds for 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 not a hundred percent pump will every result in insufficient fuel instinctive delivered to the engine. Might afterward be worth cleaning out the idle eagerness run motor / valve as these get clogged happening past carbon and some brake cleaner washed through helps release things off.
Hello the TPS does have an effect on switching the car into idle mode so I'd suggest to make positive the throttle plate is 100% closed and not slightly beached subsequent to carbon. and later acclimatize the TPS hence that the IDL stick is continuous to the E2 stick similar to the throttle is closed, and admission circuit as soon as the throttle is just cracked. Don't bother about any voltages, the IDL door is the really important one.
