Check compression. It should be well over 100 PSI and not vary by more than 15% highest to lowest.

ok, if it low or high what would the soultion be

If the compression is low in one or more cylinders, put about a teaspoon of light oil into the cylinder and check again. If the compression comes up, you have bad piston rings. If not, you most likely have bad valves and either need to replace one or both, or need to have a valve job performed.
