Hello the TPS does have an effect on switching the car into idle mode in view of that I'd suggest to create determined the throttle plate is 100% closed and not slightly beached gone carbon. and after that acclimatize the TPS as a result that the IDL glue is continuous to the E2 glue subsequent to the throttle is closed, and get into circuit behind the throttle is just cracked. Don't badly affect approximately any voltages, the IDL door is the in reality important one.
