When rps sit over 3k for some time and let car engine brake I'm getting the wonderful blinking engine and cyl 4 misfire. Dealer replaced coil and plug last week. Still getting it. Code has not hard set since coil and plug were replaced but I usually get it at least once a day. Any thoughts? Just uploaded my tune today from Kevin. Any thoughts? __________________ 2011 Mustang GT Premium The Go Fast: Magnaflow 3" OA \| Pypes X-Pipe \| Steeda CAI \| VMP Tune \| BBK Cat Deletes \| SVT GT500 quad mufflers \| The Ride & Look Good: Ford K Springs \| BMR Adj.
