My car idles rough when stopped in drive

SOURCE: ROUGH IDLE / ENGINE SURGE

Check for vacum leaks on hose going from the intake to the brake booster. Also check the dodge.com website. Click on the for users button. Enter in last eight digits of vin and see if pcm (computer) needs a update, or if there is any other open recalls on the van.

I would think the idle speed control valve is defective.

SOURCE: 88 dodge dakota has rough idle and stalls at slow down.

Change/thoroughly clean the idle control solenoid. It may be sticking and causing rough idling.
Cleaning it is unlikely to be more than a short-term solution.

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.
