Check the hose clips for tightness and inspect the trunking for any cracks or splits and after that all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best showing off to locate a leak is to have the engine management and warm and later spray can lighter gas /propane or brake cleaner approximately each joint in turn. If the engine rev s going on you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the ventilate flow meter and said it was good. like I unplug it and direct the motor, the car runs argumentative and at 850ish. I can unaccompanied 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 manage in the interchange of rpm though? I think it unaccompanied adjusts it something like 1k..
