What info do i need to change spark plugs on a 2004 jeep cherokee

Firing order doesn't change on its own and then cause misfires. Did you change something? Most likely cause is spark plugs.

R&R COIL RAIL AND THE SPARK PLUGS ARE UNDER THE RAIL, BECAUSE EACH PLUG SHOULD HAVE ITS OWN COIL(COIL RAIL IS A ONE PIECE)

If you havent changed the spark plugs, id start there.

I own a 2004 jeep Grand Cherokee 4.7 V-8 It took me 3 1/2 hours to complete changing the spark plugs. First one must remove the cover from the air filter and to the carbuetor there are two bolts on each side of the cover over the engine then the driver side is easy to remove the boots on each plug the passenger side is pretty easy except for the last plug all the way on the back this one took me 1/2 to remove because there is lots of obstructions like the power steering line and the oil line and electrical cables.

They are on the heads, follow the plug wires.

Governor Pressure Sensor Offset Volts Too Low or High

this has coil over plug (c.o.p.) ignition.you do have to pull the 8 coils to get to the plugs.
