2006 Chrysler Town & Country. Cylinder 5 misfire. Can’t get rid of it. Replaced plugs, wires, injectors, injector wiring harness, coil, crank position sensor. Still there!
Did you do a compression test before you spent all that money? or at least swapped the injector with another cyl.
Do a compression test, if low, follow it with a wet compression test on that cylinder. If dry test is low, could be valves or bad rings. If the compression comes up on the wet test it is the rings.
