HI, The belly bumper lid has to come off as a couple of demean headlamp assembly bolts are located at the rear it. Here are directions keep amused recall to rate utility using the rating page appropriately 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. with I unplug it and direct the motor, the car runs coarse and at 850ish. I can single-handedly 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 all this. I don't think the tps has that much run in the swap of rpm though? I think it isolated adjusts it regarding 1k..
later I start the car, the engine surges occurring amongst 1200 and 2000 rpm incite and forth. I tainted the IAC and the TPS when no alter 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 subjugate the rpm and it would keep for a while. Now, the engine is all the time surging to the dwindling where I cannot steer it for fright of damage to the steer train. Any experienced solution?
