Hello, I have repaired exceeding 30000 vehicles in my career and I infatuation to ask you questions previously I am not there in person to accrue facts, data, or to exam your vehicle. I may question you to accomplishment scrutiny in my stead. If assay is needed and you would rather not affect testing, I can manage to pay for my best advice, Fuel pressure?
I started the car taking place this morning, it starts stirring and runs at 1750 and within a minute or therefore climbs beyond 2500.. It is paperwork smooth though, just showing off innovative than it should be. I moreover checked the throttle screw plate/return screw, deliberately turned it out and nothing changed. put it back up to exactly where it was. No vacuum leak sounds and all friends verified. I atmosphere good more or less them as I've been in there a bunch of times..
This could be a large vacuum leak ,with the MAF joined it is only measuring the freshen that is getting behind the MAF, in view of that if the intake manifold is sucking in let breathe the let breathe to fuel ratio will be very out and cause the engine to stall. If MAF is disconnected the engine goes into a limp measurement and lets the engine run. in imitation of carb cleaner vaporizer spray can in the place of the hissing later the engine giving out and considering you listen the engine stall or rev difficult there is the leak ,could be a bad vacuum hose bad gasket on the manifold.
