(help) I need help i put a circuit sports j-pipe on and ran the car for 3 to 4 days without mil eliminator then got cel. So i put one on. It was fine for about a week. it was hesitating bad under high boost. so i finally figured out it was the plugs they where all fouled up. so i replaced them and also took j-pipe off but left mil eliminator on. about 2 weeks later plugs where fouled up again and same problem. I can't figure it out. should i take it to the dealer? (help)
