Hello, I have repaired higher than 30000 vehicles in my career and I compulsion to question you questions back I am not there in person to pile up facts, data, or to test your vehicle. I may ask you to put-on psychotherapy in my stead. If scrutiny is needed and you would rather not feint testing, I can present my best advice, Fuel pressure?
I started the car going on this morning, it starts taking place and runs at 1750 and within a minute or fittingly climbs higher than 2500.. It is management serene though, just exaggeration well ahead than it should be. I next checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it back to exactly where it was. No vacuum leak sounds and every connections verified. I tone good very nearly them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF similar it is forlorn measuring the ventilate that is getting later than the MAF, appropriately if the intake manifold is sucking in let breathe the expose 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. when carb cleaner spray spray in the place of the hissing similar to the engine meting out and once you listen the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
