2020 Shelby GT500 Intermittent Power Loss FINALLY Solved!

My 2020 Shelby GT500 has been plagued with intermittent misfires & power loss for MONTHS! DTC code P0351, Pending, Current Ignition Coil A Primary/Secondary Circuit. Multiple trips to the dealer for testing have been a challenge as the problem wouldn’t always reveal itself when there. Just when I’d think the problem was solved, it would pop-up again later. We finally found the underlying issue and it’s now FIXED!

Ironically, a friend with CFTP GT500 experienced the exact same problem at the track… same misfire, same power loss & same code. Having just solved the issue, I knew what it was and was able to show him what was needed to get back out for more track fun!
