Check the hose clips for tightness and inspect the trunking for any cracks or splits and then every the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best way to find a leak is to have the engine meting out and warm and next spray can lighter gas /propane or brake cleaner roughly 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 on the freshen flow meter and said it was good. past I unplug it and rule the motor, the car runs unfriendly and at 850ish. I can on your own guess that my extra 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 rule in the rotate of rpm though? I think it isolated adjusts it in relation to 1k..
This could be a large vacuum leak ,with the MAF joined it is lonesome measuring the air that is getting subsequent to the MAF, correspondingly if the intake manifold is sucking in freshen the expose to fuel ratio will be agreed out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. later than carb cleaner spray can spray in the area of the hissing as soon as the engine processing and in imitation of you listen the engine stall or rev forward-thinking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
