missfire

I have an 87 samurai , after driving for about an hour or so it missed and lost power to the point of pulling off the road . Found a spark plug lead lose , stuck it back on and all was fine for about 20 mins then same thing again . Checked the leads , all were ok so I got back in and drove home , 1 hour , no problems . A few weeks later same thing just not as bad , only after a a long drive . And agian today twice but both times was in 5th gear with foot on the floor up hill . Though it was electrical but now I think its fuel . Anything I should check first , whats the weak link ? Any help to save a bit of time would be great . Only gets driven about 10 mins to work each day so no problems only seems to be long trips which I do not do very often
Thanks Monty

Re: missfire

When ignition coils get hot they are prone to shorting turns
which lowers output voltage and because Sam coils are Horz and
oiled filled they run hotter and have shorten lifespan.
Replace coil with solid epoxy type or re position new oil filled
coil to vertical plane.

Re: missfire

Did it seem to loose power and the more you floored it it just kept slowing down.If it did it probably was icing the carb.Usually this is in cooler damp weather but I have seen it happen on a summer day to.I know the cover on the carb isn't easy to wip off so it would probably melt away before you could look.Make sure your thermostatic air cleaner is hooked up and working properly.If it occurs again pull over and shut it off for about 2-3 minutes then fire it up and it will run like a champ.If it does you have probably found your problem.

If it gets too deep drive faster
