Question about Jeep Cars & Trucks
What have you checked to find the misfire on cylinder 3? It can be a bad IGN coil, bad spark plug, fuel injector issue or something mechanical. Doubtful it's caused by the fuse box issue

Code P0301 is a generic OBD Code for Misfire. It also indicates you have a misfire in the #1 Cylinder. I would start by checking the plug wire to make sure its clean and on all the way (at the coil as well). Then if that doesnt help I would pull the plug out and check the condition of the spark plug. hopefully this will give you some direction. Thanks for Using FixYa!

the check engine light wont come on for the fuel filter.it comes on when the computer detects a problem from one of the many sensors.the best way to find out why the light comes is to go to autozone they will check it for free and let you knowthe problem is....

It is possible that the squeeling you heard was the alternator belt squeeling and belt might have slipped/or broke off. If the alternator belt comes off or slips the electrical system will lose voltage and this can cause weird things to happen on the dash like the engine light coming on and the oil pressure gauge dropping. Inspect the belts for proper tension and wear. It is possible something may have came up from the road and got caught in the belt or alternator housing. Did you ever restart the vehicle? Did the vehicle act normally after?
