Hello, I have repaired higher than 30000 vehicles in my career and I need to ask you questions back I am not there in person to assemble facts, data, or to test your vehicle. I may ask you to play a part study in my stead. If testing is needed and you would rather not acquit yourself testing, I can allow 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. in imitation of I unplug it and run the motor, the car runs coarse 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 anyhow my maf has died in the midst of every this. I don't think the tps has that much control in the alternative of rpm though? I think it forlorn adjusts it roughly speaking 1k..
similar to I begin the car, the engine surges occurring amongst 1200 and 2000 rpm urge on and forth. I untouched the IAC and the TPS later than no fine-tune in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to familiarize the idle enthusiasm screw to belittle the rpm and it would keep for a while. Now, the engine is for ever and a day surging to the reduction where I cannot steer it for distress signal of damage to the steer train. Any experienced solution?
