Just picked up a B3000 truck. Runs and drives great, besided the idle issue. On cold start it idles at 1000 like it should. After warmed up I believe it is about 750. The problems is when Im driving down the road and come to a stop after the truck has warmed up. I will being coming to a stop. Push the clutch in and throw it in neutral to coast. The RPMs will drop below 500 and it makes the lights dim, the truck choke, and the oil pressure gauge will even shutter. then back up to 750 im assuming some sort of Vac leak. I just replaced the IAC but no change. Any ideas or common issue on this truck.
