Looking for some help here. I have a 2017 WRX, the car has a full 3” Turbo Back Exhaust, Cobb CAI, and Cobb tuner. I randomly had an issue where my car will start great but immediately kill itself. Sometimes taking multiple times to actually run. Then you can feel a miss while driving. The car will not throw a code. I replaced the spark plugs hoping it would be a simple fix, no. If anyone can help me out here and point me in the right direction would be greatly appreciated!
