The DTC code reads P0302 "or cylinder 2 misfire. I have changed the spark plugs, wires, cap and rotor. I have re-set the computer but the problem still exists. I assume the since the truck still runs, it isnt a coil problem, I was thinking it could be an injector problem. My questions I have are:
1. What else should I be looking at?
2. Can you only change one injector?, and Is there a way to test the existing injector?

Thank you for any advice on this matter.

Off the top of my head I don't know the resistance value for dodge injectors, GM is 11.8-12.6 at 60 degrees, test with an ohm meter, Check my sig file there is a link to Mitchell manuals try it...

2001 FSM 12 ohms + or - 1.2 ohms at 68 degrees F. Might try switching the injector to see if the misfire follows? Same symptoms after the tune up as before?
