Check the hose clips for tightness and inspect the trunking for any cracks or splits and moreover all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best way to locate a leak is to have the engine dispensation and warm and then vaporizer lighter gas /propane or brake cleaner around 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 upon the air flow meter and said it was good. when I unplug it and govern the motor, the car runs harsh and at 850ish. I can single-handedly 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 govern in the alternative of rpm though? I think it without help adjusts it on the subject of 1k..
This could be a large vacuum leak ,with the MAF similar it is deserted measuring the let breathe that is getting past the MAF, fittingly if the intake manifold is sucking in expose the ventilate to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. like carb cleaner vaporizer spray can in the place of the hissing as soon as the engine admin and following you hear the engine stall or rev forward-thinking there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
