'Sup everyone.
Newbie here... just picked up a 2000 suburan about two weeks ago, my first lifted truck! Three inch body lift, six inch suspension, dual fox shocks in each corner... oh yeah, whipple charger too! ;)

Anyways, there are a few issues with it but I just started getting a P1415 Emissions code (air pump)? Does anyone have some suggestions for a fix?
