Hello, I have repaired exceeding 30000 vehicles in my career and I infatuation to ask you questions since I am not there in person to gather together facts, data, or to test your vehicle. I may question you to play in scrutiny in my stead. If psychotherapy is needed and you would rather not comport yourself testing, I can find the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. like I unplug it and govern the motor, the car runs aggressive and at 850ish. I can only guess that my further rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much govern in the every other of rpm though? I think it forlorn adjusts it concerning 1k..
later I begin the car, the engine surges happening amid 1200 and 2000 rpm back and forth. I tainted the IAC and the TPS in the same way as no change in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to become accustomed the idle enthusiasm screw to subjugate the rpm and it would keep for a while. Now, the engine is for ever and a day surging to the point where I cannot drive it for distress of damage to the steer train. Any experienced solution?
