Hi everyone. I have done some research on my 05 T&C when I started getting the P0306 code. I clear it and it typically comes back about once a week typically exactly 7 days later. Here's what I have done so far.

- Replaced all spark plugs and wires
- Replaced ignition coil
- Replaced both valve cover gaskets (the back one is completely new since I cracked it) and have a new PCV valve and hose
- Replaced the EGR valve

I am not for sure what else I can do. Is there anyone out there that can help? And yes typically in the morning is when I feel the most issues where it definitely shutters a little bit but then typically works itself out. No smoke at all. Other than that occasional stuttering, the check engine light coming on, and a lot of the times when in drive and at idle it does seem to be a little rough, there's nothing else going on.

Thanks for your help!!

 

No P0300 (multiple cylinder misfire) correct? Must be something particular to #6. Next comes fuel injector operation and compression. Can you feel the injector click as it runs?

 

No other code comes up. And not for sure how to tell if the injector clicks. How do I tell?

 

Remove whatever needed to get at it then just hold your finger on it while the engine is running. Should feel a vibration as it clicks. That or hold a screw driver tip on it then cup your ear to the handle and listen for the click.

 

P0300 is a general misfire(no specific cylinder position) code. RECHECK plug wire firing order on the cap. I'd bet some are in the wrong position.
