What engine? on the 4.0l they are on pass side of engine under a long plastic cover with 5 15mm bolts and a plug at back for the coil packs and all come off in one piece so after all the bolts are out gently work the thing up a little at a time working your way down until it world free,easy job to do just be careful of any wires you might pull on and heater hoses need to be held out of the way.

The spark plugs always go into the cylinder heads. Check at your heads and you will see the spark plug wires just follow them right to the plugs. Your car does not have a distributor because the newer cars have what is called distributorless ignition systems. The system uses sensors and the computer in your car to operate the engine,

Fuel system control open at 4000 rpm


p0306?
misfire means, low combustion energy on #6
  1. bad spark,
  2. bad injection,
  3. bad compression
there are tests for each one.

i always check compression first. that why i dont spend a fortune
guessing. 30min.,labor , done wide open throttle, 150psi min.

i also heck the fuel pressure doing the SOP leak down test. (fSm)
then the injector balance test at same time.
finds leaking injector and clogged.
got cops?
you could have swapped coil packs COPs to see if that cured mifire.
swap any other with #6
if problem follows the coil pack COPS, then its bad.
my v6 had a 3 coil pack and cant swap just one coil. all 3 or none.

the misfire is real. you can feel it and the PCM measures it.

Trying to trouble shoot why my performance is lacking or hesitating on my 1994 Jeep Grand Cherokee Larado? It has had a recent oil change, new plugs, air filter etc. all fluids are normal and I have no...


Change the following:

oil, tranny fluid, and filters: air filter and fuel filter as well. Fill up tank and add 1 can of SeaFoam. Change spark plugs, wires, coil wire if distributor is present - as well as cap and rotor.

If coil packs are present, repalce the plugs and wires, air filter, fuel filter, and have the catalytic converter tested to make sure it's not plugged. This test will also let you know if the O2 sensor(s) are bad or not.

Please let me know if you need any further assistance.

NOTE: start with the cheaper: air and fuel filter. Then work your way up.
