i'm guessen if you have an older cat that it could be haven problems. i have had that happen on two vehicles now and i could be somethen like that. check it out. don't like consider that gospel cause it could be in the fuel system or the ignition system. check for a loose coil wire or somethen.

It's running stupid rich. I would say that you have an injector that is freezing up. Have them professionally cleaned.
