My 2001 had the same symptom caused by the idle air control (IAC) valve that bypasses the carb butterfly valve. A straight-forward DIY job.

I said straight-forward ... not easy. :-) It's right on top and involves a couple of bolts, electrical connectors, and vacuum hoses - check YT videos. I just wanted to make you aware that DIY (or a mechanic friend) might be an option rather than a shop or dealer ($$$). The OEM part is pricey. Good Luck!
