I have a 3.9L V6 Dakota the has a ruff idle. The truck has 60,000 miles on it. Any common problems I can fix myself?

 

I think all of them have rough idles, but if you have a really rough idle you should take the air filter housing cover off, then have someone press the gas pedal (with the engine turned off) and look down the intake manifold. If you see any oil in it you have an internal vacuum problem, you just need to replace a gasket. If there is no oil in the intake, then that isn't your problem.
