rpm surging at idle
i cant seem to figure this one out. the rpm's bounce around at idle from 500 to 1200 rpm. this is an intermittent issue and i cant seem to find a pattern. also the car will die every now and then when i slow down kinda fast. any idea what causes this?

Re: rpm surging at idle
I'd say you're loosing pressure in your fuel system, that's why you have the surging idle and the stalling under hard braking. Have your pressure checked to see if it is at least 40 lb. psi. Possible causes, a weak fuel pressure regulator, leaking injector, kink in your line(s), etc.
