Hello, I have repaired more than 30000 vehicles in my career and I habit to ask you questions past I am not there in person to accrue facts, data, or to test your vehicle. I may ask you to appear in testing in my stead. If breakdown is needed and you would rather not perform 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. behind I unplug it and run the motor, the car runs prickly and at 850ish. I can single-handedly guess that my supplementary rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much govern in the alternative of rpm though? I think it without help adjusts it re 1k..
considering I start the car, the engine surges up amid 1200 and 2000 rpm assist and forth. I changed the IAC and the TPS in imitation of no tweak 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 readiness screw to degrade the rpm and it would support for a while. Now, the engine is constantly surging to the dwindling where I cannot steer it for distress signal of broken to the drive train. Any experienced solution?
