    "service engine soon" code-303 (missfire on no three cylinder)- light keeps comeing on and after I drive it for a few days it goes off then the same again in a few days. I've changed vaccum line;s under the hood. putnew spark plugs & wireing, new coil, & new GM gas cap,- the only thing I haven't checked is the vaccum lines to canister and canister

    Check engine light came on just before the inspection was due. Had the code read. The guy at the parts place recommended replacing the gas cap first. It did the trick.
