# 2 cylinder missfiring?

[fishnhuntnboy]

So this has been going on for quite sometime and i have changed the spark plugs (all of them) and i replaced the coil pack for that spark plug. I have a 2001 dodge dakota with a 4.7 lt and each plug has its own coil pack. I still get the code popping up and then it resets itself after a few days. I have also put in fuel injector cleaner but still dont seem to help. I am at a complete stump of what it is and I dont want to take it in and spend a ton of money for a shop to try and figure it out also.

Thanks for all the help

If the injector is fouled bad enough it will take more than a cheap bottle of injector cleaner. Might need to be cleaned professionally. The bypass the fuel pump and run the engine on an injector cleaning machine. Also check the wire going to #2 coil.

I would bet you have valve issues!

Thanks for the responses. How would i find out if it is a valve problem? Also I am going to take everything apart again this weekend and double check the plug.

I would think you would have to pull a valve cover to check the valve.

If the plud and coil look good, the first thing I would do is a compression check. If that was good than I would swap the coil with another cylinder. If the misfire follows the coil than you know the coil is the problem. If the misfire stays you could always swap the injectors and see if the misfire follows.

I agree, swap coils, even thought you replaced it doesnt mean it works right. Always change the coil and make sure the misfire follows the coil pack.

very good post airjer

thanks for the help guys. i will have to change to coil around and see if that does it. otherwise i will have to look around and do some of the other stuff.
