Sample Wiring Diagram

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super present car that I am ready to steer 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 aggravating 2-3 vary 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. assist 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 once 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 need to be re-adjusted? The master tech did every sorts of diagnostics on all related parts (tps, maf, iac). $100-200 all times I understand it get the dealer for diagnostics.. on going problems are really add-on up. I m hesitant to lie alongside 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 little more about the difficulty history. It currently has a master tech recognized idle expose control valve and tps installed. without heartwarming anything, the last (used) ecu and my original, would run in the car without this symptom.

Hello the TPS does have an effect upon switching the car into idle mode suitably I'd suggest to make sure the throttle dish is 100% closed and not slightly high and dry later than carbon. and then accustom yourself the TPS therefore that the IDL glue is continuous to the E2 attach later the throttle is closed, and right to use circuit later than the throttle is just cracked. Don't cause problems not quite any voltages, the IDL approach is the really important one.
