Switch Wiring Guide

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 problem that I researched online and did tests (per the manual) upon tps, iac and maf and cleaned the TB. After frustrating 2-3 stand-in 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. put up to to the dealer.. this epoch he says, it needs a ECU. I did a lot of research on them, and found that its a common problem subsequent to this car.. bought a used one.. more trouble. had the indigenous 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 obsession to be re-adjusted? The master tech did every sorts of diagnostics on all related parts (tps, maf, iac). $100-200 every era I give a positive response it attain the dealer for diagnostics.. upon going problems are truly adding together up. I m unsure to lie alongside the tps if he had it dialed. Any insight? Thanks in advance. Jason


I bought it in July, drove it house from LA (to Utah), and the problems started rapidly after I got it home.Any additional urge on you can pay for is appreciated. I don’t know what else to attain but allow it back up to the dealer. I know I’ve got the shop foreman keen on it at the dealer, but I yet tone its pushed to the support as its outdated and everyone loses in this situation.

taking into account I begin the car, the engine surges taking place amongst 1200 and 2000 rpm encourage and forth. I misrepresented the IAC and the TPS as soon as no modify in symptoms. I have noticed that several Lexus SC’s have this thesame issue. Prior to this I would have to get used to the idle promptness screw to humiliate the rpm and it would maintain for a while. Now, the engine is for all time surging to the narrowing where I cannot drive it for warning of damage to the drive train. Any experienced solution?
