    Diagnostic code 18

    I recieved a check engine light on sunday, noticed a considerable performance loss about a min or two before the actual light. I was nearing the end of a race so backing off the throttle was not an option.

    Finally it died on me, would start right back up no problem but would die with any throttle. Had to push it up onto my trailer. Started it up out of the water and it would idle funny till I gave it gas, then the idle cleared up. I pulled the plugs hoping they were fouled but they looked alright to me.

    What does the code "18" indicate?

    I've replaced the plugs and it seems to idle and rev fine right now, but I havent had a chance to put it back into the water.
