3.7 2006 coil dropping out?

[danabryant1979]

Got a 2006 3.7 i replaced the heads on and now i get coil 6 that seems to drop outat random times. I moved the coil and plug but the issue stays at cylinder 6. Any ideas?

Engine does have a mysterious hesitation now as well.

Wiring, internal damage, bad lifter (lash adjuster) Bad rocker. Based on your trace, I am going with wiring.

These things are older than dirt and the wiring is always suspect IMO. Those little connectors on the coil is where I would start. There is a thing called a ‘noid’ lamp that plugs into the harness and blinks. No blink, bad wire or connector. Note - the bad end may be at the coil, or trace back to the next connector.

Thank you for the info. Do you perhaps know where I can find a wiring diagram for the coils?
