Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super shout from the rooftops car that I am ready to steer 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 maddening 2-3 alternative 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 time he says, it needs a ECU. I did a lot of research on them, and found that its a common problem next 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 compulsion to be re-adjusted? The master tech did all sorts of diagnostics upon all related parts (tps, maf, iac). $100-200 all time I consent it do the dealer for diagnostics.. upon going problems are in reality adjunct up. I m of two minds to touch the tps if he had it dialed. Any insight? Thanks in advance. Jason

Might also be worth checking the wiring and connector to the airflow meter for any signs of corrosion or damage. you can reach a fast defect find if you unplug the meter and direct the engine without it. if the engine condition is the same then chances are the meter or the link to it is faulty. Its afterward worth cleaning the MAF sensor wires, as they can get coated similar to dirt higher than become old which later offsets the reading. Use some gate cleaner or brake cleaner to vaporizer onto the wires to sever the dirt on no account adjoin the wires gone everything as they are entirely fragile

Hello the TPS does have an effect upon switching the car into idle mode suitably I'd recommend to create sure the throttle plate is 100% closed and not slightly stranded in the same way as carbon. and then become accustomed the TPS consequently that the IDL glue is continuous to the E2 glue following the throttle is closed, and retrieve circuit in the same way as the throttle is just cracked. Don't distress very nearly any voltages, the IDL edit is the essentially important one.
