Is my coil pack faulty?

[petermorling]

Hey people i just went and changed my spark plugs today, (anybody got a first aid box....) when i fired it up it seems to have a slight misfire when you push the throttle from idle. When the plugs were changed 4,000 miles ago 3 coil packs were replace, however when i took out the plug at the rear left hand side the plug was very sooty could this be the coil pack that wasnt replaced last time? Any help or advise would be gratefully appriciated.

 

Many Thanks

Cant help with the technical question.  But out of interest, why are you changing your plugs after 4000 miles?

Are your plugs definately in the right place?

ie Doing one plug at a time ensures that they are put back in the right place

yip, i've done plugs a million times before, it was doing the misfire before the plug change, i am changing them as it has been over a year since they were changed and for the sake of £25 its pice of mind.

if u suspect coil pack u could try wrapping some electrical tape round the rubber of it, as this is what normally deterioates i believe.
