SOURCE: My jeep liberty threw a code:P0303 Cyl #3 Misfire
#3 cylinder is either 3rd from fron on front to back engine or third from left on sideways engine (assuming 4 cylinder engine) misfire could be fouled or bad plug, injector fouled, bad coil, bad wire, bad sensor...lots of things can cause this. I would have all codes cleared and then see if it comes back and if it does what other codes show up as well.
the PCM knows how to fire them, its hard coded
there is no distributor.
my guess, is you scrambled the coil packs?
my 3.7L (its in USA) has 6 coil packs, called cops.
and can not ever be scrambled. ever.
ours is the WK jeep.
firing order is.
1 - 6 - 5 - 4 - 3 - 2
number one on all V engines is the most front cylinder
one is more front if you look at them.. left front is 1
the v6 has 6, cops coils
the v8 small same.
the V8 big has 3 cops with shared wasted spark crossover wires.
are you confused on what engine you have?>?
3.7L
page on in the FSM chapter 9
The cylinders are numbered from front to rear with the left bank being numbered 1,3, and 5
and the right bank being numbered 2,4, and 6. The firing order is 1-6-5-4-3-2. The engine serial number is
located at the right front side of the engine block
Drivers perspective, seated. (just like saying left car door)
