Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super publicize car that I am ready to drive off a cliff. had a idle surge suffering that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After grating 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. yet had issues. back to the dealer.. this era he says, it needs a ECU. I did a lot of research on them, and found that its a common hardship following 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 craving to be re-adjusted? The master tech did all sorts of diagnostics on every partnered parts (tps, maf, iac). $100-200 every times I allow it get the dealer for diagnostics.. upon going problems are in reality adjunct up. I m in two minds to adjoin the tps if he had it dialed. Any insight? Thanks in advance. Jason
