Check the hose clips for tightness and inspect the trunking for any cracks or splits and furthermore all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best exaggeration to find a leak is to have the engine government and warm and after that spray lighter gas /propane or brake cleaner just about 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 upon the freshen flow meter and said it was good. gone I unplug it and govern the motor, the car runs harsh and at 850ish. I can only guess that my extra 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 rule in the vary of rpm though? I think it solitary adjusts it around 1k..
This could be a large vacuum leak ,with the MAF aligned it is on your own measuring the air that is getting in imitation of the MAF, fittingly if the intake manifold is sucking in ventilate the air to fuel ratio will be no question out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. following carb cleaner spray vaporizer in the area of the hissing in imitation of the engine government and next you listen the engine stall or rev forward-thinking there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
