2000 Dodge Dakota Question: Recurring misfire on #2

 

Question

My check engine light comes on and the engine begins misfiring. Scan shows #2 misfire and something about Ign. coil B Primary/Secondary circuit. Replacing the plug always solves the problem. Except that it will happen again anywhere from one month to two minutes. This is getting verrrry tiresome. Suggestions?
I have already swapped coils to see if the problem moved with it. It didn't.

    How does the plug look when the misfire reappears?

    If the plug lasts long enough it will have a tan appearance around the insulator and the ground electrode.
    If the plug fails shortly after installation it has no appearances other than looking quite new.
    Codes retreived are P0302 and P0352.

    What are the exact codes you are getting?

    You may want to have this checked by a shop that has experience with Dodger vehicles. Continuing to drive with a misfire will damage the catalytic converter, which can run $1000.00+

    I do not drive with the misfiring plug. I replace it at the earliest possible opportunity.
