For those that don't know i have a willy 3 engine in my valver shell on 75k.
I've noticed over the last month or so that there's a strange misfire. Not when you start it, and not when you drive it normally, just when you boot it.
It only seems to happen in second gear (possibly third too), and it just seems to miss when i hit 5000RPM, feels as though i hit the limiter and jolts the car quite violently.
Any ideas what this could be?
I'm going to try swapping the rotor arm, dizzy cap, and leads from my valver engine as they're pretty much brand new.
Could it possibly be coil pack?
Thanks for any ideas!
