got a 97 zj with the 5.2 in it and it runs like crap i get 10.5 to 11 on expressway and it idles funny too. recently replaced the plugs 3 months ago, and the cap and rotors and plug wires less than a month ago. Well last week i threw codes for cylinder 1, 2, and 8 misfire. When i pulled them out, cylinder 8's spark plug electrod was chipped and coated in oil well put e3 spark plugs in monday and today took cylinder 8 spark plug out to see what it looked like and its coated in oil again not much but it shouldn't being looking like that after 4 days....Is there anyone on here that has had the same problem i am having this would help me alot.
