I have a 1996 Jimmy 4x4 limited edition? the problem is when I stop some times the engine off, but I see the RPM goes 600 to 1500 rpm and lose sometimes the force and then off. Im desesperate for this...


It might be the egr valve acting up. You can try unplugging it and see if the problem is corrected. The Check engine light will come on if you do unplug it. It won't hurt the truck to try.

My 1996 GMC jimmy wants to stall when I come to a stop. The RPM gage goes up & down then drops below 1000 RPMS and stalls.


I would go down to your local auto parts store and do an alternator and battery test. It sounds like at low rpms you are loosing volts. When you apply the brakes you would be supprised how much power from the engine it takes. You could also be loosing oil pressure. Check your oil level. When your engine drops low rpm, the oil pressure drops and shuts down the engine.

1996 GMC Jimmy, flutters when in idel


You could have a cloged EGR valve on the jimmy, which can be removed and cleaned with carb or injector cleaner which you can buy at any parts store.
As for the air leak on the brake system on the truck. That's bad and needs to be replaced or repaired, taking a guess that the sevice brake valve gaskets may be bad.
Good luck and hope this helps.
