I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. in the manner of I unplug it and run the motor, the car runs prickly and at 850ish. I can lonesome 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 control in the swing of rpm though? I think it solitary adjusts it in relation to 1k..
in imitation of I begin the car, the engine surges going on amongst 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS once no fine-tune in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle zeal screw to demean the rpm and it would keep for a while. Now, the engine is each time surging to the reduction where I cannot drive it for frighten of broken to the steer train. Any experienced solution?
