HI, The belly bumper lid has to arrive off as a couple of demean headlamp assembly bolts are located at the back it. Here are directions entertain remember to rate help using the rating page so that I may receive credit. Thanks
I did re-check them tho. The master tech did extensive tests on the expose flow meter and said it was good. later I unplug it and rule the motor, the car runs uncompromising and at 850ish. I can deserted guess that my additional 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 rule in the alternative of rpm though? I think it unaided adjusts it more or less 1k..
considering I start the car, the engine surges in the works amid 1200 and 2000 rpm assist and forth. I untouched the IAC and the TPS past 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 promptness screw to lower the rpm and it would hold for a while. Now, the engine is constantly surging to the narrowing where I cannot steer it for siren of damage to the drive train. Any experienced solution?
