MasterYou could still have a vacuum leak from the intake manifold for example. Or there could be an un-metered air leak from a broken air tube or air box.
Or - you could have weak fuel pressure - check base fuel pressure also.

Visitor, March 26, 2011, 23:35Most people check for vacuum leaks by having a diagnostic tool hooked up to see what the fuel trims look like, and then they "richen" the air around the intake manifold or wherever they suspect a vacuum leak. This is done by introducing a fuel like propane gas in the area. Some people use carb cleaner or similar.
You could have a throttle body issue (very dirty) or an idle air control valve issue too.
