Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super promote car that I am ready to drive off a cliff. had a idle surge pain that I researched online and did tests (per the manual) upon tps, iac and maf and cleaned the TB. After frustrating 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. yet had issues. support 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 suffering next 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 need to be re-adjusted? The master tech did every sorts of diagnostics upon all amalgamated parts (tps, maf, iac). $100-200 every time I assume it reach the dealer for diagnostics.. upon going problems are truly tallying up. I m undecided to be adjacent to the tps if he had it dialed. Any insight? Thanks in advance. Jason

Its next worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a under the weather pump will all consequences in insufficient fuel physical delivered to the engine. Might plus be worth cleaning out the idle eagerness govern motor / valve as these get clogged going on afterward carbon and some brake cleaner washed through helps release things off.

Hello the TPS does have an effect upon switching the car into idle mode thus I'd suggest to make clear the throttle plate is 100% closed and not slightly beached in the same way as carbon. and next adjust the TPS as a result that the IDL pin is continuous to the E2 stick as soon as the throttle is closed, and read circuit past the throttle is just cracked. Don't make miserable practically any voltages, the IDL door is the really important one.
