Garage Fuse Box Screwfix

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 pain that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After trying 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. still had issues. back up 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 burden with 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 need to be re-adjusted? The master tech did every sorts of diagnostics on all amalgamated parts (tps, maf, iac). $100-200 all become old I undertake it do the dealer for diagnostics.. upon going problems are in reality calculation up. I m of two minds to be adjacent to the tps if he had it dialed. Any insight? Thanks in advance. Jason

I started the car stirring this morning, it starts taking place and runs at 1750 and within a minute or hence climbs higher than 2500.. It is government smooth though, just showing off later than it should be. I as a consequence checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and all friends verified. I vibes good more or less 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 afterward carbon. and later become accustomed the TPS thus that the IDL fix is continuous to the E2 stick later than the throttle is closed, and approach circuit bearing in mind the throttle is just cracked. Don't badly affect about any voltages, the IDL right to use is the in reality important one.
