I'm not sure of the other prospects on it.
You can try to find the problem by checking the vacuum of the fuel pressure regulator, if gas is coming up the tube instead of air, it may prove the diaphram of the regulator is cracked.
For what it matters, if you contact a local snap-on dealer
www. Snapon. Com
he can refer you to an independent garage that can work on them. The aftermarket works hard to keep up by necessity.
Another possiblity is a carbon build up that soaks the gas before it burns it, this should be done regardless of the symptom:
I would try what I call an air induction service.
I like to use castle hydroblast. You spray it into a vacuum line such as the brake booster line if nothing else is accessible. Full spray for 3 minutes, stall the engine with it or have somone kill it while your spraying. Let it set for a few hours then take for a short drive in low gear, revving the rpms to help break it up. First use Castle cleansrite to clean the throttle bore. Try to get the throttle plates scrubbed good with a brush, while your spraying. Use a rag to wipe the carbon out between brushngs. Seafoam is another good product, but smokes a lot.
IF you can't find Castle, here is my rep's email:
