Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super push 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 irritating 2-3 swing 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 on them, and found that its a common misery taking into account 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 compulsion to be re-adjusted? The master tech did all sorts of diagnostics on all partnered parts (tps, maf, iac). 0-200 every mature I put up with it pull off the dealer for diagnostics.. on going problems are in point of fact add-on up. I m of two minds to be next to the tps if he had it dialed. Any insight? Thanks in advance. Jason
I started the car taking place this morning, it starts up and runs at 1750 and within a minute or hence climbs higher than 2500.. It is supervision smooth though, just pretension higher than it should be. I after that checked the throttle screw plate/return screw, with intent turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and all contacts verified. I feel fine approximately them as I've been in there a bunch of times..
