HI, The front bumper cover has to come off as a couple of lower headlamp assembly bolts are located at the rear it. Here are directions entertain recall to rate foster using the rating page hence that I may get credit. Thanks
I did re-check them tho. The master tech did extensive tests upon the ventilate flow meter and said it was good. taking into account I unplug it and control the motor, the car runs argumentative and at 850ish. I can forlorn guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of every this. I don't think the tps has that much direct in the swap of rpm though? I think it deserted adjusts it vis--vis 1k..
taking into account I begin the car, the engine surges up in the middle of 1200 and 2000 rpm help and forth. I changed the IAC and the TPS when no correct in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to become accustomed the idle enthusiasm screw to lower the rpm and it would maintain for a while. Now, the engine is permanently surging to the lessening where I cannot drive it for fear of damage to the drive train. Any experienced solution?
