My engine is missing. The engine codes say "random multiple misses" "Cylinder 2 and 7" I changed the plug, and wire on number 7 but no change. I then changed the distributor cap but still no change and the codes read the same. What should I check now?

U WILL NEED TO DO A COMPRESSION TEST. TO CK. FOR A DEAD MISS THAT CAN BE CAUSED BY A VALVE OR BAD RINGS. U ARE NOT GOING TO REPAIR THIS BY THROWING PARTS AT IT. U HAVE REPLACED EVERYTHING ALL READY!! THEN IF U CAN'T FIND IT U WILL NEED TO PUT IT ON A SCOPE
