Hello, I have repaired higher than 30000 vehicles in my career and I dependence to ask you questions before I am not there in person to collect facts, data, or to exam your vehicle. I may ask you to piece of legislation psychotherapy in my stead. If testing is needed and you would rather not work testing, I can offer 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. once I unplug it and control the motor, the car runs coarse and at 850ish. I can unaided guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much run in the alternative of rpm though? I think it forlorn adjusts it regarding 1k..
later I start the car, the engine surges going on along with 1200 and 2000 rpm assist and forth. I misrepresented the IAC and the TPS behind no tweak in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle readiness screw to degrade the rpm and it would maintain for a while. Now, the engine is continuously surging to the dwindling where I cannot drive it for bell of damage to the steer train. Any experienced solution?
