Check the hose clips for tightness and inspect the trunking for any cracks or splits and along with every the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best showing off to find a leak is to have the engine organization and warm and next vaporizer lighter gas /propane or brake cleaner with reference to each joint in turn. If the engine rev s in the works you ve found your leak.
I did re-check them tho. The master tech did extensive tests upon the air flow meter and said it was good. later I unplug it and control the motor, the car runs argumentative and at 850ish. I can solitary 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 control in the every second of rpm though? I think it lonesome adjusts it not far off from 1k..
gone I start the car, the engine surges going on amid 1200 and 2000 rpm support and forth. I misrepresented the IAC and the TPS following no bend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to familiarize the idle rapidity screw to demean the rpm and it would support for a while. Now, the engine is for all time surging to the reduction where I cannot drive it for alarm bell of damage to the drive train. Any experienced solution?
