Hey Scotty, I have a 2001 Dodge Dakota Sport 3.9L Magnum 2WD Extended Cab with over 162,000 Miles on it and I was wondering if you could help me resolve my issue here. So recently my truck shut off on me while waiting at a stop light and I addressed and fixed the issue with the spark plugs pre gaped to spec, wires, and distributor and new idle control sensor.

A week after giving the truck a small engine tune up, I had 2 Codes pop up and found I had a Misfire in Cylinder 5. Which being the hardest to get to knowing it’s next to the master cylinder. So I research on how to fix it but the spark plug is on right and gapped right and the wire plug for the cylinder is snug on top of the spark plug. And still I’m getting a heavy idle and same codes.

What do you think this could be apart of? Is it a bad spark plug or wire, or does this have to be a problem with the Distributor? I made sure everything was put on carefully and precisely I’m just confused on what to do. If you could help me that would be great!!!

I also have more problems to ask on a later date. But this problem is the main to be concern about before emissions.

fuel injector problems often trip misfire codes, as do blowing head gaskets or leaking intake manifolds at that cylinder. Check those first
