Hey guys, so I'm having a issue with my 2003 cobra. The left exhaust sounds weird I thought it was going to be a exhaust leak but I was told no. I was told that it could be my coils or plugs. Car has 27k miles and has 2.76, jlt cai, exhaust, E85 tuned. Engine is kinda shaky but not too much plugs I have are NGK. Any tips? It's pretty much just the idling when the car sits still. Car just got tuned by Bob kurgan
