What is wrong with my 2004 Grand Chrokee?
3 weeks ago I threw a code for a cylinder 1 misfire. it went away on its own after 2 days before I could get it checked. The day after it went away, my battery guage starting bouncing from 12.5 to 15.5 consistently. I made sure all my connections were tight and the needle stuck at just under 14. 2 days after that I htrew a cyclinder 1 misfire again. This lasted 9 days and the battery guage was fine. 2 days ago the check engine light went out on its own again and the battery guage started jumping around again.
