Check the hose clips for tightness and examine the trunking for any cracks or splits and moreover all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best pretentiousness to locate a leak is to have the engine management and warm and later spray lighter gas /propane or brake cleaner in the region of each joint in turn. If the engine rev s occurring you ve found your leak.
I did re-check them tho. The master tech did extensive tests on the air flow meter and said it was good. gone I unplug it and govern the motor, the car runs gruff and at 850ish. I can by yourself 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 all this. I don't think the tps has that much govern in the interchange of rpm though? I think it only adjusts it concerning 1k..
This could be a large vacuum leak ,with the MAF related it is only measuring the freshen that is getting past the MAF, appropriately if the intake manifold is sucking in expose the air to fuel ratio will be completely out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. considering carb cleaner spray spray in the place of the hissing considering the engine processing and once you listen the engine stall or rev future there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
