I have an XR4i and it has a misfire. I`ve started checking for a spark at each lead and that is fine. This has caused me to believe it is head related.

I have taken off the H.T leads off one at a time to try and find which valve it is. Whenever i take the a lead off on the passenger side, it mis fires a bit more which i think should happen, but if i take a lead of the drivers side, the misfire dosn`t get any worse...

Has anyone ever expirenced this on the cologne before?

Do i need a new engine?, Head? etc ?????

Someone please help me........!!

Cheers, Ed.
