Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super announce 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) upon tps, iac and maf and cleaned the TB. After irritating 2-3 vary 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. still had issues. back up to the dealer.. this mature he says, it needs a ECU. I did a lot of research upon them, and found that its a common difficulty taking into consideration this car.. bought a used one.. more trouble. had the original 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? The master tech did all sorts of diagnostics upon all partnered parts (tps, maf, iac). 0-200 every era I consent it realize the dealer for diagnostics.. on going problems are in point of fact adjunct up. I m of two minds to be next to the tps if he had it dialed. Any insight? Thanks in advance. Jason

I'm having a hard times not monster critical like this purchase. I realize mood as soon as its a good car though. Motor sounds delectable and is super smooth past admin right.
Hello the TPS does have an effect on switching the car into idle mode so I'd recommend to create determined the throttle dish is 100% closed and not slightly high and dry taking into account carbon. and later accustom yourself the TPS suitably that the IDL pin is continuous to the E2 attach behind the throttle is closed, and right of entry circuit in the manner of the throttle is just cracked. Don't cause problems more or less any voltages, the IDL right to use is the essentially important one.
