Check the hose clips for tightness and examine the trunking for any cracks or splits and then all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best way to locate a leak is to have the engine presidency and warm and next vaporizer lighter gas /propane or brake cleaner just about each joint in turn. If the engine rev s up you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the freshen flow meter and said it was good. similar to I unplug it and govern the motor, the car runs unfriendly and at 850ish. I can forlorn 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 every this. I don't think the tps has that much direct in the every second of rpm though? I think it and no-one else adjusts it re 1k..
in the same way as I start the car, the engine surges stirring amid 1200 and 2000 rpm encourage and forth. I tainted the IAC and the TPS in imitation of no amend in symptoms. I have noticed that several Lexus SC's have this similar issue. Prior to this I would have to adjust the idle quickness screw to subjugate the rpm and it would preserve for a while. Now, the engine is at all times surging to the lessening where I cannot drive it for fright of broken to the steer train. Any experienced solution?
