:driving:well, it sounds like a ring may have stuck and possible broke, do a compression test, i'm sure you'll find a difference in compression. pull the spark plugs, put in about an ounce of tranny fluid in each cylinder let it sit overnight, then spinn the motor over to spit out what might be left, the reinstall plugs and fire it up, its going to smoke if that doesnt free the rings up, ie. it still misses pull the dist cap and check your pickup coil inside the dist
also with a lo mileage engine sitting for awhile valves could be stuck in there guides, try some sea foam, if the tranny fluid dont work
