For the 3.8L engine...1, 3, 5, are on the ideal side, front to back, looking at the engine from the driver"s seat.2, 4, 6, are on the left side, front to back, looking at the engine from the driver"s seat.The firing order is 1, 2, 3, 4, 5, 6.However, the plugs are fired in pairs: 1 & 4; 2 & 5; 3 & 6.In each situation, the cylinder that is not on the compression stroke sees a "wasted spark" on its exhaust stroke.
is there a diagram of the spark plugs or just how to readjust them? I likewise am a newby and desire to adjust them. Please provide me some direction
Do a google search for "Jeep JK spark plug change".. provides you web links to write-ups on various other sites. Pretty simple to do. You will need a 5/8" spark plug removal socket and a long ratchet expansion and also a swiveling socket adapter to get to some of them.If you are replacing the wires, be careful with the plastic wire manager tabs, they break quickly. Also number and change the brand-new wire lengths as you remove the old wires one at a time.Takes an hour tops... Good luck!
