2.5L I4 Idles Rough

[obxbronco]

The Comanche i'm getting idles rough when sitting still. Idles ok at higher rpm's, and drives fine. Could it be vacuum leak or something?

Plug wires, plugs, coolant in combustion chamber, dist cap and rotor.

Clean the idle air control valve first. Vac leak will cause problems almost everywhere.

pretty much all the vacuum lines are screwed up. Broke, cut, etc.....

Fix them, or don't bother troubleshooting anything until you do.
