Try checking the integrity of the various vacuum hoses as they dry and crack. also make sure the the air intake boot that leads to the throttle body is stight at the clamps and that there are no cracks in the boot. you can also try spraying wd-40 around various areas of the intake system to check for a leaking manifold gasket. To do this, with the engine running, spray wd-40 around suspected areas of the leak, if the engine tone changes, (ie smooths out then runs rough) you have isolated a leak to that area. Hope this helps.
