Hello, I have repaired exceeding 30000 vehicles in my career and I infatuation to ask you questions back I am not there in person to gather together facts, data, or to exam your vehicle. I may question you to bill psychoanalysis in my stead. If testing is needed and you would rather not enactment testing, I can present 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 poorly pump will every upshot in insufficient fuel creature delivered to the engine. Might with be worth cleaning out the idle zeal direct motor / valve as these get clogged happening with carbon and some brake cleaner washed through helps clear things off.
Hello the TPS does have an effect upon switching the car into idle mode suitably I'd recommend to make sure the throttle dish is 100% closed and not slightly high and dry in the manner of carbon. and after that acclimatize the TPS suitably that the IDL stick is continuous to the E2 fix when the throttle is closed, and gain access to circuit in imitation of the throttle is just cracked. Don't distress more or less any voltages, the IDL contact is the in fact important one.
