I have a 2004 fx4 with 131k miles and i was driving home from work the other day and the engine warning light came on and it was juddering at around 40 ish or when you tried to accelerate.

When i came to a stop it wasnt idling correctly was was obviously missing.

I had it plugged in and it returned the code p0306 so its missing on pot 6...

i then drove home and it is no longer missing and has none of the symptoms that it had before


why could this have happened??

what do i need to do to prevent it happening again??

thanks,

sounds like a bad coil pack to me

welsh boy

the coils are all on individual plugs on these motors arent they??

would it be worth changing all the plugs and coils???

how much would i be looking at paying for that??
