Super market car that I am ready to steer off a cliff. had a idle surge pain that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After trying 2-3 alternative used IAC s, I took it to the master tech at lexus. He said it was the IAC valve. He tried my used ones.. and finally a rebuilt one. nevertheless had issues. assist to the dealer.. this grow old he says, it needs a ECU. I did a lot of research upon them, and found that its a common pain gone this car.. bought a used one.. more trouble. had the indigenous one rebuilt by a specialist.. and that s where I am at now.. Put it in tonight and the car idles at 2k rpm. Does the TPS need to be re-adjusted?

I don't know what else to attain but take on it back to the dealer. I know I've got the shop foreman working upon it at the dealer, but I nevertheless air its pushed to the back up as its dated and everyone loses in this situation.

Hello the TPS does have an effect upon switching the car into idle mode in view of that I'd suggest to create definite the throttle dish is 100% closed and not slightly high and dry later carbon. and subsequently get used to the TPS hence that the IDL glue is continuous to the E2 fix gone the throttle is closed, and admission circuit subsequently the throttle is just cracked. Don't worry about any voltages, the IDL get into is the essentially important one.
