Super make public car that I am ready to steer off a cliff. had a idle surge problem that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After grating 2-3 every second 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. encourage 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 trouble in the same way as 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 infatuation to be re-adjusted?

I started the car in the works this morning, it starts in the works and runs at 1750 and within a minute or therefore climbs over 2500.. It is management mild though, just quirk superior than it should be. I with checked the throttle screw plate/return screw, on purpose turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and every associates verified. I atmosphere good practically them as I've been in there a bunch of times..

Hello the TPS does have an effect on switching the car into idle mode fittingly I'd suggest to make clear the throttle plate is 100% closed and not slightly ashore past carbon. and subsequently acclimatize the TPS consequently that the IDL fasten is continuous to the E2 attach bearing in mind the throttle is closed, and read circuit gone the throttle is just cracked. Don't bother virtually any voltages, the IDL contact is the essentially important one.
