Hello, I have repaired higher than 30000 vehicles in my career and I habit to ask you questions past I am not there in person to assemble facts, data, or to test your vehicle. I may ask you to enactment psychoanalysis in my stead. If psychoanalysis is needed and you would rather not take steps testing, I can present my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the expose flow meter and said it was good. past I unplug it and direct the motor, the car runs scratchy and at 850ish. I can lonesome guess that my additional 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 stand-in of rpm though? I think it single-handedly adjusts it all but 1k..
as soon as I begin the car, the engine surges up amongst 1200 and 2000 rpm support and forth. I tainted the IAC and the TPS once no tweak in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to become accustomed the idle swiftness screw to humiliate the rpm and it would maintain for a while. Now, the engine is for ever and a day surging to the dwindling where I cannot drive it for bell of damage to the steer train. Any experienced solution?
