I'm getting my car back from service tomorrow. I had misfires with my JB4 installed but they couldn't replicate it without it so they replaced the spark plugs in good faith but wouldn't do injectors or coil packs. Can the valves be causing the misfires also? I have 48k miles on the car so i think they'll be pretty bad... If so and my wheels sell i'm gonna do this through you guys
