Ok my 2003 5.9 dakota has a rough idle and no excelleration power when getting on freeway,I'm stumped,is it engine ,exhaust or tranny,help would be appreciated, ty.

 

Does it idle rough as soon as you start it? Or does it run good for a couple minutes, then start getting rough? Any codes? Still have a cat? Last time it had a tune-up?

 

Ok. That could be correct but the big line I’m referring to is headed forward and is actually melted near the firewall where it appears to have started to head upwards. There are actually 3 lines that come off the canister. This bigger one and 2 smaller ones. One of the smaller lines goes to the purge valve and the other one heads back and up from the canister. I did not trace this line yet to be sure but I assumed it was the one that went up to the fuel tank but I could be wrong.
