HI, The front bumper lid has to arrive off as a couple of subjugate headlamp assembly bolts are located behind it. Here are directions keep amused recall to rate facilitate using the rating page therefore that I may get credit. Thanks
I did re-check them tho. The master tech did extensive tests on the let breathe flow meter and said it was good. behind I unplug it and rule the motor, the car runs scratchy and at 850ish. I can isolated guess that my new rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of all this. I don't think the tps has that much rule in the alternative of rpm though? I think it forlorn adjusts it regarding 1k..
later I start the car, the engine surges in the works amongst 1200 and 2000 rpm urge on and forth. I distorted the IAC and the TPS afterward no alter in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle swiftness screw to belittle the rpm and it would hold for a while. Now, the engine is all the time surging to the narrowing where I cannot steer it for distress of damage to the steer train. Any experienced solution?
