Check the hose clips for tightness and examine 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 mannerism to locate a leak is to have the engine organization and hot and later spray can lighter gas /propane or brake cleaner something like each joint in turn. If the engine rev s taking place 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. next I unplug it and direct the motor, the car runs rude and at 850ish. I can abandoned guess that my other rebuilt ecu has an issue, or the tps needs to be re-adjusted, or anyhow my maf has died in the midst of every this. I don't think the tps has that much manage in the oscillate of rpm though? I think it lonesome adjusts it with reference to 1k..
This could be a large vacuum leak ,with the MAF combined it is by yourself measuring the let breathe that is getting in imitation of the MAF, for that reason if the intake manifold is sucking in freshen the let breathe to fuel ratio will be entirely 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 vaporizer vaporizer in the area of the hissing taking into consideration the engine handing out and next you listen the engine stall or rev highly developed there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
