If it idles worse when its cold......Intake gaskets are known to cause this symtom. If it they have never been replaced.....I would replace them as a maintainence item at 148K.

+1 on the intake gaskets.....I've run in to two of them in the last few months. The best way to know for sure is to use a smoke machine and smoke the intake....you'll see smoke coming out at the gasket if you have a problem
If you do the intake gaskets, I would recommend getting the better Fel-pro gaskets that are molded rubber over steel frame instead of the stock plastic holder with a seal.....do it once and be done with it
