Check the hose clips for tightness and inspect the trunking for any cracks or splits and also every the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretension to locate a leak is to have the engine organization and hot and subsequently spray can lighter gas /propane or brake cleaner on the subject of each joint in turn. If the engine rev s stirring you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. in imitation of I unplug it and manage the motor, the car runs rasping and at 850ish. I can solitary guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or someway my maf has died in the midst of all this. I don't think the tps has that much control in the swap of rpm though? I think it on your own adjusts it vis--vis 1k..
in imitation of I begin the car, the engine surges up in the company of 1200 and 2000 rpm put up to and forth. I misrepresented the IAC and the TPS bearing in mind no amend in symptoms. I have noticed that several Lexus SC's have this same issue. Prior to this I would have to adapt the idle eagerness screw to subjugate the rpm and it would withhold for a while. Now, the engine is constantly surging to the reduction where I cannot drive it for radio alarm of damage to the drive train. Any experienced solution?
