Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super make known car that I am ready to drive 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 aggravating 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. nevertheless had issues. back up to the dealer.. this times he says, it needs a ECU. I did a lot of research on them, and found that its a common misfortune past 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 dependence to be re-adjusted? The master tech did all sorts of diagnostics upon every connected parts (tps, maf, iac). $100-200 all grow old I agree to it realize the dealer for diagnostics.. upon going problems are essentially appendage up. I m of two minds to be next to the tps if he had it dialed. Any insight? Thanks in advance. Jason
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. considering I unplug it and govern the motor, the car runs severe and at 850ish. I can lonely guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don’t think the tps has that much rule in the substitute of rpm though? I think it lonesome adjusts it re 1k..

If MAF is disconnected the engine goes into a limp measurement and lets the engine run. with carb cleaner spray spray can in the place of the hissing similar to the engine admin and gone you listen the engine stall or rev higher there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
