When driving on the highway between 45 & 65 mph, the engine skips periodically. I had the sparkplug wires changed and distributor replaced, new plugs. Dosen't skip while accerlerating, just when driving on the highway between 45 & 65 mph. Doesn't do it all the time. After it's warmed up and cruising is when it starts to skip, but on the return trip it doesn't skip at all. What could be causing this problem?

Start by checking all the vacuum lines for cracks/loose connections.

Small vacuum leaks can cause intermittent missing.
