You have a BIG vacuum leak somewhere. Could be your gas cap, also could be the hoses to and from the charchol canister under the truck--drivers side. The solenoid for it is up front drivers side. If any of the hoses are questionable at all, replace them for the vacuum canister---seen this post many times before---I'm doing mine before winter this year.
