Hello, I have repaired more than 30000 vehicles in my career and I craving to question you questions before I am not there in person to build up facts, data, or to exam your vehicle. I may question you to accomplish breakdown in my stead. If laboratory analysis is needed and you would rather not work testing, I can have the funds for my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. behind I unplug it and run the motor, the car runs aggressive and at 850ish. I can single-handedly guess that my other 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 rule in the swap of rpm though? I think it and no-one else adjusts it approximately 1k..
as soon as I begin the car, the engine surges happening surrounded by 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS past no fiddle with in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adjust the idle zeal screw to lower the rpm and it would sustain for a while. Now, the engine is continuously surging to the point where I cannot drive it for startle of damage to the drive train. Any experienced solution?
