Hi all!!

did a trackday at Cadwell yesterday and found when warm and at 5000rpm i had a misfire would drop onto 2-3 cylinders then if i kept revving it would clear and run sweet. I checked everything over and found two large cracks in the dizzy cap. My question is would these two cracks cause a intermittant misfire.

Many thanks Gary

More than likely. I had a car that did the same and that was a cracked cap.

If the cap's cracked it's a wonder it doesn't misfire all the time.

Well it was getting worse and worse so only did two sessions in the morning.

Swap the cap and rotor arm together when you do the job, it's not worth trying to save on.

Just been and ordered new items getting rotor arm aswell as there is not alot left of it!
