Jump under the hood and work the throttle by hand. The cable from the gas pedal pulls forward on the passenger side of the throttle body assembly, and the lever it pulls on pulls on the cable that goes down to the transmission. Check that the cable going down to the transmission moves freely and doesn't bind or kink when you release the throttle.
Probably the best thing to lube it with, on both ends, is Mopar MP-50. It is very similar to WD-40, but WD-40 is meant more to dissolve rust and MP-50 is more of a lubricant. It's thin enough to soak in easily and it tends to dissolve bug juice and thickened grease.
