1998 Dodge Ram What would cause misfire on cylinder 3 &

Hi there, normally a miss fire on parent cylinders can be a vacuum leak at the inlet port near those cylinders, a combustion leak between the cylinders, or you may just have a simple tune issue, start with the tune and work from there.

Hi there,

I need to get access to Mitchell 1 first, this I can only do at home, as it is early afternoon here in Aust, I won't be home for a few hrs yet, but I will do this as soon as I can.

Hi there have been having a re think on your problems your engine set up like in the pic with the distributor at the rear, if so see that No 3& 4 are next to each other in the distributor cap, so i would first be checking for any spark jumping at the cap terminals, just start the engine and look at it in the dark if it is jumping you will see it, give it a few revs as well, failing that check under the cap and look for any fine cracks and tracking lines between these two posts on the cap, start here.
