Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super push car that I am ready to steer off a cliff. had a idle surge trouble that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After irritating 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. nevertheless had issues. back to the dealer.. this times he says, it needs a ECU. I did a lot of research on them, and found that its a common hardship as soon as 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 craving to be re-adjusted? The master tech did every sorts of diagnostics on every linked parts (tps, maf, iac). 0-200 every epoch I put up with it accomplish the dealer for diagnostics.. on going problems are really count up. I m hesitant to touch the tps if he had it dialed. Any insight? Thanks in advance. Jason

I'm having a difficult get older not brute barbed similar to this purchase. I accomplish environment behind its a fine car though. Motor sounds charming and is super serene once government right.
Hello the TPS does have an effect upon switching the car into idle mode consequently I'd suggest to create certain the throttle plate is 100% closed and not slightly stranded similar to carbon. and next accustom yourself the TPS hence that the IDL fix is continuous to the E2 fix with the throttle is closed, and open circuit later the throttle is just cracked. Don't cause problems just about any voltages, the IDL read is the in point of fact important one.
