5 3l Wiring Diagram

Hi, this car is kicking everyone s ass.. 92 lexus sc400. 128k. Super spread around car that I am ready to drive off a cliff. had a idle surge hardship that I researched online and did tests (per the manual) on tps, iac and maf and cleaned the TB. After aggravating 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. incite to the dealer.. this get older he says, it needs a ECU. I did a lot of research upon them, and found that its a common hardship subsequent to 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 need to be re-adjusted? The master tech did every sorts of diagnostics upon every joined parts (tps, maf, iac). $100-200 all times I say yes it attain the dealer for diagnostics.. upon going problems are in fact additive up. I m in two minds to be adjacent to the tps if he had it dialed. Any insight? Thanks in advance. Jason


Its plus worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a not at your best pump will all consequences in insufficient fuel brute delivered to the engine. Might with be worth cleaning out the idle eagerness manage motor / valve as these get clogged going on bearing in mind carbon and some brake cleaner washed through helps pardon things off.

Hello the TPS does have an effect on switching the car into idle mode therefore I'd suggest to create clear the throttle plate is 100% closed and not slightly stranded subsequent to carbon. and subsequently get used to the TPS correspondingly that the IDL fasten is continuous to the E2 fasten later than the throttle is closed, and right of entry circuit considering the throttle is just cracked. Don't distress nearly any voltages, the IDL log on is the in reality important one.
