My 07 has the check engine light on. I ran a scan and the code for multi misfire in cylinders came up. The Jeep will run rough now and then as well. If I stop and restart it usually runs fine after that ? I replaced the plugs,o2sensors ,cat convert, air filter, cleaned intake ,checked for vacuum leaks. I was going to replace fuel filter but its in the tank with fuel pump. Any ideas on what next to try ? That's engine code.......lol

Welcome to the form, you posted your question in the KL Cherokee Technical area, you will probably get a better answer in the Grand Cherokee Technical area. Common error, Cherokee and Grand Cherokee but they are two different vehicles.
