I have an '03 Durango. I did a tune up on my truck and right after it started to make a ticking noise under the hood. I can hear it in the cab and sometimes it vibrates real bad but it only does it when it's in gear even when I'm sitting still in gear. What's the deal.

 

please post in the 1st gen section so that it gets more page views.

 

What plugs did you use and were they gapped to .040?
