Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super spread around car that I am ready to drive off a cliff. had a idle surge difficulty that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After frustrating 2-3 substitute 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. yet had issues. urge on to the dealer.. this epoch he says, it needs a ECU. I did a lot of research upon them, and found that its a common burden later 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 every sorts of diagnostics upon every related parts (tps, maf, iac). $100-200 all mature I agree to it attain the dealer for diagnostics.. on going problems are truly tally up.

I started the car up this morning, it starts up and runs at 1750 and within a minute or as a result climbs higher than 2500.. It is presidency serene though, just showing off later than it should be. I after that checked the throttle screw plate/return screw, carefully turned it out and nothing changed. put it encourage to exactly where it was. No vacuum leak sounds and every links verified. I setting fine practically them as I've been in there a bunch of times..

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