Sounds to me like an ignition problem.

Could be as simple as a loose spark plug wire, or pinched wire shorting out before it gets to the spark plug.

Have a tuneup done on it. At a different shop!!

I used to drive a car that did about the same thing. I would add something to take water out of the gas now and then in hopes that it would eventually stop, and it finally did. But it seems reasonable that I probably also began filling up somewhere else (it was over ten years ago so my memory of the problem has faded) and that using different gas is what helped.

I don't know if it matters, but that car was a Chevrolet with a carburetor instead of fuel injectors.

ah my friend, i think u should find another mechanic. my buddy the mechanic once said that mechanic in a can is no mechanic at all. drop the 85 bucks and have the dealer diagnose it. u might throw a new distributor cap and rotor at it for next to nothing. u got nothing to lose. do me a favor, try using bp gas and see what happens. it worked for my cars. drop me a line if it works. thanks alot. rob

Ask your mechanic whether it could be an ignition misfire.
