My 2013 Jeep Wrangled JK Unlimited Sports 4 door has the check engine light staying on. I have taken the negative off the battery and changed out all the 6 spark plugs. Then, I replaced the computer system, and changed out the entire sensor 5 harness for the spark plug. Hooked the negetive all back up to the battery, and still it is staying there is a misfire. I had autozone hook up the computer to diagnose and it still statutes a 0305 misfire. Can some one tell me what is the next steps I need to do to get this code to go away? What's the order I guess in ease and cheapest to most difficult and expensive. Thanks for reading and help me out!!!
