Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super broadcast car that I am ready to drive 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 maddening 2-3 exchange 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. help to the dealer.. this get older he says, it needs a ECU. I did a lot of research upon them, and found that its a common misfortune with 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 habit to be re-adjusted? The master tech did every sorts of diagnostics upon all related parts (tps, maf, iac). 0-200 every time I understand it pull off the dealer for diagnostics.. upon going problems are truly tallying up. I m of two minds to touch the tps if he had it dialed. Any insight? Thanks in advance. Jason

Its then worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a poorly pump will all repercussion in insufficient fuel physical delivered to the engine. Might as well as be worth cleaning out the idle rapidity manage motor / valve as these acquire clogged happening in imitation of carbon and some brake cleaner washed through helps release things off.

I don't have any check engine lights unless I unplug the MAF sensor. with the MAF is plugged in then the car will stall unless I put my foot upon the accelerator. There is as well as an intermittent popping unquestionable coming at idle.
