Check the hose clips for tightness and examine the trunking for any cracks or splits and as a consequence all the vacuum system, the little bore pipes and fittings for cracks and missing parts. The best mannerism to find a leak is to have the engine supervision and warm and later spray can lighter gas /propane or brake cleaner a propos each joint in turn. If the engine rev s going on 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. once I unplug it and manage the motor, the car runs uncompromising and at 850ish. I can without help guess that my new 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 rule in the vary of rpm though? I think it on your own adjusts it roughly 1k..
This could be a large vacuum leak ,with the MAF linked it is isolated measuring the expose that is getting in imitation of the MAF, suitably if the intake manifold is sucking in ventilate the freshen to fuel ratio will be utterly 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 can spray in the area of the hissing taking into consideration the engine doling out and next you hear the engine stall or rev progressive there is the leak ,could be a bad vacuum hose bad gasket upon the manifold.
