Hello, I have repaired higher than 30000 vehicles in my career and I craving to question you questions previously I am not there in person to assemble facts, data, or to test your vehicle. I may question you to comport yourself testing in my stead. If assay is needed and you would rather not perform testing, I can have enough money 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. following I unplug it and run the motor, the car runs rasping and at 850ish. I can forlorn guess that my new 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 manage in the vary of rpm though? I think it and no-one else adjusts it on 1k..
subsequent to I start the car, the engine surges happening amid 1200 and 2000 rpm back up and forth. I misused the IAC and the TPS following no bend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle swiftness screw to humiliate the rpm and it would maintain for a while. Now, the engine is every time surging to the lessening where I cannot drive it for fear of damage to the drive train. Any experienced solution?
