Hey gang, I have a 1994, ford e-350, v-8, I have a small skip in my engine, i have replaced my wire, plugs, gave it a great tune up but it still skips, I even change the distributor just in case, but still with no luck. It does not skip all the time just once in a while, I could be at idle and it runs fine then about every 2 to 3 minutes I get a skip. Any ideas out there?? thanks

 

Check for vacuum leaks around the upper plenum to lower manifold with carb cleaner. If it runs fine other than that, I wouldn't sweat it.
