Are there any recent mods you just did?
A couple of things that come to mind.
1. Make sure the egr tube is connected. It's a black tube that goes from the air intake tube to the valve cover. It could be this or another vacuum line pulled. There's one that goes to the brake booster also.
2. Throttle position sensor. You can hook a voltmeter up to the wires and open and close the throttle body. The meter should move and stay within a certain limit. A manual can give more detailed specifics.
