Default 4.0 trouble

Ok so my 4.0 is giving me a lil bit o trouble... It drives fine but when I stop at a light or sit for too long she starts to idle funny... Almost like a sputter, it usually idles round 1000 but when it acts up it drops to 500 and then will shut off... I think it just needs a new fuel filet and the injectors cleaned to solve it but wanted some other ideas.

From what I hear it may need a tune up, if the miles are decently high, it may need all its fluid changed, spark plugs, coils, fuel filter, etc. have they been done recently?

Clean your throttle body, that is a common problem on the 4.0.
