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 running and hot and after that spray can lighter gas /propane or brake cleaner in this area each joint in turn. If the engine rev s in the works you ve found your leak.
Thanks for your response. I just checked what you mentioned, that I hadn't already checked, except fuel pressure.Let me tell you a little more just about the hardship history. It currently has a master tech credited idle expose manage valve and tps installed. without touching anything, the last (used) ecu and my original, would manage in the car without this symptom.
This could be a large vacuum leak ,with the MAF amalgamated it is forlorn measuring the air that is getting in the same way as the MAF, correspondingly if the intake manifold is sucking in freshen the let breathe to fuel ratio will be unconditionally out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in imitation of carb cleaner spray spray can in the place of the hissing as soon as the engine doling out and afterward you listen the engine stall or rev highly developed there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
