Hi I'm new to the forum but I'm wondering if anyone can help. I have a 1988 xr3i cabby which is doing my head in. It will run ok for couple of days then when I go to start it the next day it has a bad misfire( only firing on 3), after maybe an hour of messing with leads and plugs-swapping them about, it will start up again with no problems - anybody had this before cheers stu

 

If I was you id change leads plugs etc for new ones and go from there.

 

Cheers for reply. Plugs all been changed, and borrowed leads from a pal and didn't make difference
