Yep, thats the diffrence between fuel cut and missfire, the air / fuel reading on a missfire would be rich from the unburt fuel that the plug is missing.
In a Fuel cut you will see the air / fuel reading jump all the way lean, cause there is NO fuel for that 1 second cut. This is not a gapping problem or missfiring problem. Leaking IC piping results in missfires if i remember correctly, not fuel cuts. Dropped a note on www.mckinneymotorsports.com hopfully they can pull through for me. but still, please keep idea's coming...
Thanks!
