Change the pcv valve this will cause problems. You can get the eighth plug, put the socket on the plug and use a wrench that fits the socket to get it loose or out. It's a pain but necessary.

My 1997 Jeep grand cherokee is running real rough when I accelerate. Now while driving it it keeps stopping but will start right back up? help???


check the cables of the spark plugs, some times it occurs that the cables get loose from its plastic retainers and touch any metal in the engine, causing missfire of the related spark plug, hence rough running of the engine. Put all cables on the retainers making sure none touches the bare metal of the engine. That should help.

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


You will need to know that it is a 2004 Jeep Cherokee (or either Grand Cherokee, but they should have same engine) and the engine code. That is the 8th character in your VIN number. Parts store can then get you the right plugs and let you know the correct gap to set them at. IF you do not want to mess with setting the gap you can get BOSCH DOUBLE PLATINUM plugs, they will not need to be set.

I replaced my spark plug wires on my 1996 chevy truck. may have crossed one,need a diagram from the spark plugs to the distributer cap.


Since you didn't state whether it is a V6 or V8, I'll give you both.

V6 -4.3Liter
Firing Order is 1-6-5-4-3-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap, faces the front of the engine.

->Drivers side, spark plug order in engine, starting from the Front going back:
1-3-5
->Passenger side, spark plug order in engine,
starting from the Front going back:
2-4-6

If it's Electronic, the distributor cap has a Left side, (Drivers side), and a Right side, (Passenger side)
Starting from the Front, going back on the Left side,
3-1-5
Starting from the Front going back on the Right side,
2-4-6

V8-5.0, 5.7, and 7.4Liter
Firing Order is 1-8-4-3-6-5-7-2
Distributor rotor turns Clockwise
Number 1 spark plug tower on distributor cap,
faces Front, towards the Drivers side.

Electronic distributor cap has two sides. Drivers, (Left), side and Passenger, (Right), side.
Starting from Front going back on Drivers side,
1-7-3-5
Starting from Front going back on Passenger side,
8-2-4-6

Spark plug order in engine, starting from Front going back, Drivers side:
1-3-5-7
Spark plug order in engine, starting from Front going back, Passenger side:
2-4-6-8

Spark plugs


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.
