February 9, 200521 yr I have been corresponding with a person having an idle problem on his 2000 OBW (SOHC Phase 2 5L). The idle surges from 500rpm to 1500rpm on occasion, and runs rough when the idle falls. I did a search and only found some references to the EGR valve on older models causing a low idle, but nothing specific for this surging. Any help is appreciated...
