I have a 2005 TJ 4.0 and I joined for some help. I have a P0303 code which is cylinder 3 misfire. Things I have done so far include all new spark plugs, new coil rail, new o2 sensors, swapped the first fuel injector with the third fuel injector, and a new crank position sensor. Only thing I can think of left before I take the head off is a cam position sensor. It's not making ticking noises like a lifter tick would. It's doggy and that's about all. Any help is greatly appreciated. Thanks in advance.
