Re: Idle drops when HVAC controls are adjusted

long start could be a few things, dirty IAC dirty coolant temp sensor, and the fuel pressure regulator that snaps into the top of your fuel tank would be the first things i would check, especially if there is no check engine light on. also i think 400 rpm is a bit low for when your a/c clutch is engaged, if you haven't i would also take a look at your ground wires, my 2000 is very fussy with ground wires, especially the ground to the inner fender.
