HI, The belly bumper cover has to arrive off as a couple of belittle headlamp assembly bolts are located at the rear it. Here are directions keep busy remember to rate help using the rating page therefore that I may get credit. Thanks
I did re-check them tho. The master tech did extensive tests upon the let breathe flow meter and said it was good. subsequently I unplug it and control the motor, the car runs rasping and at 850ish. I can isolated guess that my supplementary 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 run in the interchange of rpm though? I think it forlorn adjusts it on 1k..
afterward I start the car, the engine surges happening along with 1200 and 2000 rpm support and forth. I untouched the IAC and the TPS behind 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 humiliate the rpm and it would maintain for a while. Now, the engine is each time surging to the dwindling where I cannot steer it for panic of damage to the steer train. Any experienced solution?
