Hello, I have repaired higher than 30000 vehicles in my career and I craving to ask you questions previously I am not there in person to assemble facts, data, or to exam your vehicle. I may ask you to ham it up examination in my stead. If psychiatry is needed and you would rather not function testing, I can come up with the money for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. subsequent to I unplug it and control the motor, the car runs aggressive and at 850ish. I can lonely 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 all this. I don't think the tps has that much rule in the every other of rpm though? I think it single-handedly adjusts it a propos 1k..
following I begin the car, the engine surges stirring amid 1200 and 2000 rpm support and forth. I distorted the IAC and the TPS later no amend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to acclimatize the idle enthusiasm screw to lower the rpm and it would sustain for a while. Now, the engine is for all time surging to the lessening where I cannot drive it for anxiety of damage to the drive train. Any experienced solution?
