Hello, I have repaired higher than 30000 vehicles in my career and I obsession to ask you questions since I am not there in person to collect facts, data, or to test your vehicle. I may question you to work examination in my stead. If chemical analysis is needed and you would rather not perform testing, I can offer my best advice, Fuel pressure?
Its as well as 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 all consequences in insufficient fuel inborn delivered to the engine. Might also be worth cleaning out the idle rapidity run motor / valve as these acquire clogged going on similar to 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 so I'd recommend to create positive the throttle plate is 100% closed and not slightly grounded behind carbon. and subsequently familiarize the TPS correspondingly that the IDL stick is continuous to the E2 attach like the throttle is closed, and way in circuit considering the throttle is just cracked. Don't cause problems more or less any voltages, the IDL right of entry is the in reality important one.
