So my buddy's 2000 xj idles fine and will rev up fine while sitting in park. But when you put it in gear and try to drive off it falls flat on its face.... I'm at a loss any suggestions guys???

Before you replace the MAP sensor, make sure the rubber elbow that goes from the sensor to the throttle body is not rotted or disconnected.

OP, before you replace anything make sure you've cleaned your grounds. Also the MAP sensor gets gummed up with crap from time to time, make sure it's clean inside.
