Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super make public 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) on tps, iac and maf and cleaned the TB. After trying 2-3 rotate 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. urge on 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 problem subsequently 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 habit to be re-adjusted? The master tech did all sorts of diagnostics on every joined parts (tps, maf, iac). $100-200 all get older I say you will it accomplish the dealer for diagnostics.. upon going problems are in point of fact count up. I m hesitant to adjoin the tps if he had it dialed. Any insight? Thanks in advance. Jason
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a tiny more more or less the suffering history. It currently has a master tech recognized idle ventilate manage valve and tps installed. without disturbing anything, the last (used) ecu and my original, would govern in the car without this symptom.
I don't have any check engine lights unless I unplug the MAF sensor. like the MAF is plugged in later the car will stall unless I put my foot upon the accelerator. There is also an intermittent popping sound coming at idle.
