Hello, I have repaired exceeding 30000 vehicles in my career and I obsession to ask you questions past I am not there in person to build up facts, data, or to test your vehicle. I may ask you to feign testing in my stead. If study is needed and you would rather not statute testing, I can provide my best advice, Fuel pressure?
I did re-check them tho. The master tech did extensive tests upon the freshen flow meter and said it was good. in the manner of I unplug it and govern the motor, the car runs rasping and at 850ish. I can deserted guess that my additional rebuilt ecu has an issue, or the tps needs to be re-adjusted, or somehow my maf has died in the midst of every this. I don't think the tps has that much run in the different of rpm though? I think it lonely adjusts it in this area 1k..
when I start the car, the engine surges taking place in the middle of 1200 and 2000 rpm support and forth. I distorted the IAC and the TPS next no fiddle with in symptoms. I have noticed that several Lexus SC's have this thesame issue. Prior to this I would have to familiarize the idle eagerness screw to demean the rpm and it would retain for a while. Now, the engine is until the end of time surging to the reduction where I cannot steer it for terror of damage to the steer train. Any experienced solution?
