I was on my way up to Daytona when suddenly, she begins to stumble on me. It feels almost like it shuts off for a fraction of a second. I took it to a dealer in Daytona and the problem as usual did not replicate itself. It went away for awhile and on my way back home, it did it again. No codes, no check engine light...NOTHING... but it is STILL DOING IT! HELP!!!
