how can you tell if one of your coilpacks is faulty?
sometimes get a bit of a missfire in 3rd when accelerating and doesnt seem to pull.
changed the plugs last month just wonder if maybe its a coilpack problem as its fine most of the time
only had the engine light on once that was about 8 weeks ago and it started to flash and felt like it had lost power thats what made me change the plugs
