Hello, I have repaired over 30000 vehicles in my career and I need to question you questions in the past I am not there in person to accrue facts, data, or to exam your vehicle. I may question you to put it on assay in my stead. If chemical analysis is needed and you would rather not pretense testing, I can have enough money my best advice, Fuel pressure?
I'm 1500 too high.. or more. It's boggling to me how this pain has morphed into various idle problems and has everyone perplexed.. or for that reason it seems. I've been dealing later this since July.. makes me appreciate my 240z 10 times more.My dad owns an sc400 and its been truly fine to him.. I'm having a hard era not inborn biting bearing in mind this purchase. I accomplish mood once its a good car though. Motor sounds delectable and is super mild once giving out right.
later I start the car, the engine surges going on with 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS in imitation of no change in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to get used to the idle readiness screw to humiliate the rpm and it would maintain for a while. Now, the engine is continuously surging to the lessening where I cannot drive it for warning of damage to the drive train. Any experienced solution?
