Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super market car that I am ready to steer off a cliff. had a idle surge misfortune that I researched online and did tests (per the manual) upon tps, iac and maf and cleaned the TB. After a pain 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. back up to the dealer.. this period he says, it needs a ECU. I did a lot of research on them, and found that its a common misery as soon as 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 dependence to be re-adjusted? The master tech did all sorts of diagnostics on all related parts (tps, maf, iac). $100-200 every become old I recognize it attain the dealer for diagnostics.. on going problems are truly supplement up. I m unsure to lie alongside the tps if he had it dialed. Any insight? Thanks in advance. Jason

I started the car happening this morning, it starts taking place and runs at 1750 and within a minute or for that reason climbs over 2500.. It is giving out mild though, just pretension sophisticated than it should be. I along with checked the throttle screw plate/return screw, intentionally turned it out and nothing changed. put it encourage to exactly where it was. No vacuum leak sounds and every links verified. I setting good virtually them as I've been in there a bunch of times..

Hello the TPS does have an effect upon switching the car into idle mode suitably I'd recommend to make clear the throttle dish is 100% closed and not slightly stranded past carbon. and after that familiarize the TPS so that the IDL attach is continuous to the E2 fix past the throttle is closed, and admittance circuit when the throttle is just cracked. Don't badly affect very nearly any voltages, the IDL contact is the essentially important one.
