Starts right up fine, let it warm up for about 4 to 5 min, then the check engine light come on. Turn it off and hit the key, starts right up. Check engine light is off, then in 4 to 5 mins, the check engine light comes back on. Can do this all day. Any ideas?
Tom. the engine is all stock, carb has been rebuilt, runs great, no miss no problems. New air cleaner new plugs and wires.
