Need some help on a problem that has me stumped. My '88 Ranger 4x4 2.9L V6 is only firing on 5 cylinders. #3 is not firing. I checked for spark and it is getting it and when I pulled the plug to put in a new on it was dripping with gas so it's getting fuel, maybe too much. I put my thumb on the plug hole it had my wife crank it over and it knocked my thumb off so I figure it has good enough compression to fire anyways. So that's the story. Any thoughts would be greatly appreciated.
