Hello, I have repaired greater than 30000 vehicles in my career and I dependence to ask you questions previously I am not there in person to store up facts, data, or to exam your vehicle. I may ask you to put it on testing in my stead. If chemical analysis is needed and you would rather not affect testing, I can have enough money my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. subsequently I unplug it and run the motor, the car runs sharp and at 850ish. I can on your own guess that my extra rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of all this. I don't think the tps has that much rule in the vary of rpm though? I think it on your own adjusts it concerning 1k..
later than I start the car, the engine surges in the works between 1200 and 2000 rpm incite and forth. I distorted the IAC and the TPS past no regulate in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adjust the idle speed screw to degrade the rpm and it would retain for a while. Now, the engine is at all times surging to the reduction where I cannot steer it for startle of damage to the drive train. Any experienced solution?
