as above guys, and how hard is it to test and change a coil pack?

[blackpool1974]

not sure if its

14
25
36

or

36
25
14

they are under your engine cover, takes 30 seconds to undo the electrical plug to each individual coil and pull it out

pull one out at a time and if the engine tone doesnt change when its pulled , then that is one of the knackered ones

cheers BP, so if 2 coil packs are knackered, its clearing running like crap, if i pull one of the duff 2 out, it wont change?

But if i pull a good coil out, it'll run even worse, or possible cut out?

yep you've got it, just a process of elimination.

this should help. if you're able to reset the codes and then drive for a very short distance, then check the codes again you may find it's down to just one cylinder. the faulty coil pack could have caused a 'hiccup' that caused a misfire in another cyclinder.
But even if it's both..... tadaa!
