My 2000 durango has a tough time starting. I turn the key forward and it takes an extra 3 seconds or so before the engine fires. Once the engine fires it runs a little rough until I rev it up to 2000 rpm or so and/or start driving it down the road. I have been told maybe fuel pump or oxygen sensor, any ideas??

 

When was the last tune up? Sounds like spark plugs to me.

 

I'm not sure when the last time the spark plugs have been changed, not since ive owned it and that has been about a year. what kind of spark plugs do you suggest?

 

+1. Cap and rotor WITH plugs. Don't do one without the other.

What engine are we talking about here?

 

cap???

 

Distributer cap

 

Doesn't know about the cap... must be a 4.7.

yeah it's the 4.7 engine.

 

swap the plugs and see how it goes. Use stockers or NGKs at the stock temp.
