That's my thought process as well, Joe. I don't think it's a coil though because the symptoms went away after i put that new gas cap on there......
then again, the symptoms came back
In addition to it dying 1/2 way into a "hot" lap, it wasn't idling all that smoothly & the exhaust was popping quite a bit when i was keeping the revs up... possibly as a result of a lean condition?
