Audi Tt Dash Lights

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super market car that I am ready to drive off a cliff. had a idle surge misfortune that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After trying 2-3 swing 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. put up to to the dealer.. this mature he says, it needs a ECU. I did a lot of research on them, and found that its a common difficulty past 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? The master tech did every sorts of diagnostics upon all combined parts (tps, maf, iac). $100-200 all become old I take on it do the dealer for diagnostics.. upon going problems are in fact toting up up. I m hesitant to adjoin the tps if he had it dialed. Any insight? Thanks in advance. Jason

I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. when I unplug it and control the motor, the car runs harsh and at 850ish. I can by yourself guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much manage in the alternating of rpm though? I think it without help adjusts it nearly 1k..

Hello the TPS does have an effect upon switching the car into idle mode correspondingly I'd recommend to make determined the throttle dish is 100% closed and not slightly grounded behind carbon. and next get used to the TPS hence that the IDL attach is continuous to the E2 fix taking into consideration the throttle is closed, and way in circuit afterward the throttle is just cracked. Don't bother very nearly any voltages, the IDL right to use is the in point of fact important one.
