tobyn123 Posted November 9, 2016 Share Posted November 9, 2016 Afternoon guys and girls, So a couple weeks ago I got a warning light, opened up torque pro and was informed it was cylinder 4 miss fire this happened a couple times but very intermittent - Fast forward and i bought a new coil pack - replaced and seemed fine for a few miles, Now it seems allot less intermittent and mainly running on 5 - My thought is potentially a bad spark plug, its coming upto a service and is on 103,000 so is about time for the next set - Just wondering if anyone had any other thoughts/idea/similar problems? cheers T (Current codes is P0300 + P0304) Quote Link to comment Share on other sites More sharing options...
Lewis_UK Posted November 9, 2016 Share Posted November 9, 2016 Your on the right track buddy, General diagnostics forme: Spark Plugs -> Coil Packs -> Cam/Crankshaft Position Sensors. If it's still coming P0304 (Cylinder 4) and you replaced that Coil Pack and it seems alot better, could defo be wear/tear on the spark plugs.

tobyn123 Posted November 9, 2016 Author Share Posted November 9, 2016 Im going to book it into the garage tomoz and ask for a service with sparks then (good to get the stamps in the book) If its not that and is the cam/crank shaft sensor a big job?
