Super publicize car that I am ready to steer off a cliff. had a idle surge hardship that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After a pain 2-3 substitute 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. yet had issues. back to the dealer.. this times he says, it needs a ECU. I did a lot of research upon them, and found that its a common trouble when this car.. bought a used one.. more trouble. had the native 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 craving to be re-adjusted? The master tech did every sorts of diagnostics on all joined parts (tps, maf, iac). 0-200 all epoch I agree to it realize the dealer for diagnostics.. on going problems are in reality adding up. I m of two minds to touch the tps if he had it dialed. Any insight? Thanks in advance. Jason
