SOURCE: sometimes i start my cherokee and it misfires for

Cylinder 3 AND 4 are the hottest of the straight 6 engines, the misfire is most likely caused by coolant seeping into the cylinder and shorting the plug out. If this continues it will eventually burn/blow the head gasket out from between the 3 and 4 cylinders. You will need a compression test and a radiator pressure test to determine if you have coolant seeping into the cylinder. If you do you will need a valve job (Possibly a new or rebuilt head). Also flush the cooling system out while you are in there.

Check spark plugs, leads, distributor cap & rotor arm, fuel pump, fuel filter, coil pack(s), relays, replace any items that are suspect IE Fuel filter which has probably not been changed since new even though they should be changed on all vehicles every 18 months, all of this can be done at home & will save you a lot of bucks in mechanic/garage fees,

There are a couple of bulletins from GM on valves causing these codes. # 05-06-01-030D and #PIP3063C are the bulletin #'s you need to have them look at. They are related to the valves in the cylinder head causing your exact symptoms. You should contact another dealer or GM customer assistance with this info. Good Luck
