right a couple of things. the engine was fine one night then i drove it the next moring and was mis fireing quite badly so i took it into the garage last night and they done a dio on it.witch bought up the same faults i already knew 0300 and 0305. Which they told me was random mis fire and misfire on cylinder 5. They have now said they will price it up but they are going to change the spark plugs and both coil pack. They think it will be about £300. Firstly does that sound about right and secondly the said they will have to strip it right down to get to the coil packs is this right?
To start with I would never let a garage change my plugs and coil pack as that is a job easily accomplished by even a novice, maybe referring to the guides on this forum.

To me, £300 is daylight robbery, but I suppose if you really cannot do it yourself, then you pay it! - Unless of course you can find someone on here, close to you, who could do it for beer money + parts!

Secondly though is I wonder why this problem has come on so suddenly. It could be due to the infamous cam cover gaskets leaking and allowing oil to get into your plug wells, thus they will end up overheating and misfiring. If this is the case, before the plug and coil pack are replaced, check those plug wells as that, along with the cam cover gaskets, could be the real cause of your problem!
