cylinder 5 misfire Sign In
chrysler Town and County 2005
3.8L engine NY vehicle
Check engine light codes currently active:
P0507 Idle Cntrl system RPM above expected
P0305 Cylinder 5 misfire
Things i have tried to fix for the 304 code:
i bought a new coil pack and installed it, swapped spark plugs and spark plug wires to see if the misfire would change cylinders and it did not. I checked the Ohms on the cylinder 5 fuel injector and it deemed the same as the others, nothing different showing up. Cleared code between each of these and 30 miles later the code would come back on.
Im trying to get this vehicle inspected which requires the check engine light off in NY. I am not sure what possible issues the misfire could else be?

Re: cylinder 5 misfire Sign In
Is this a constant misfire or misfire under load? Have you done a compression test? Have you check for an injector pulse on #5?

constant misfire
I swapped the fueld injectors of #5 and another one and the code stayed for #5

Re: cylinder 5 misfire Sign In
How about the presence of injector control? If you don't have control, the injector will not work. How about compression?
