well like the subject line says. The only code I got was for vac purge control solenoid but beings that the car is still in open loop doesnt that rule out a lot of different things like o2 sensors and such ?
wouldnt something like a bad vacuum line more likely be the problem ?

Code 85 - CANP solenoid - The Carbon Canister solenoid is inoperative or missing. Check vacuum lines for leaks and cracks. Check electrical wiring for loose connections, damaged wiring and insulation. Check solenoid valve operation by grounding the gray/yellow wire to the solenoid and blowing through it. The computer provides the ground for the solenoid. The red wire to the solenoid is always energized any time the ignition switch is in the run position.
Charcoal canister plumbing - one 3/8" tube from the bottom of the upper manifold to the rubber hose. Rubber hose connects to one side of the canister solenoid valve. Other side of the solenoid valve connects to one side of the canister. The other side of the canister connects to a rubber hose that connects to a line that goes all the way back to the gas tank. There is an electrical connector coming from the passenger side injector harness near #1 injector that plugs into the canister solenoid valve. It's purpose is to vent the gas tank. The solenoid valve opens at cruse to provide some extra fuel. The canister is normally mounted on the passenger side frame rail near the smog pump pulley.
It does not weigh but a pound or so and helps richen up the cruse mixture. It draws no HP & keeps the car from smelling like gasoline in a closed garage. So with all these good things and no bad ones, why not hook it up & use it?
The purge valve solenoid connector is a dangling wire that is near the ECT sensor and oil filler on the passenger side rocker cover. The actual solenoid valve is down next to the carbon canister. There is about 12"-16" of wire that runs parallel to the canister vent hose that comes off the bottom side of the upper intake manifold. That hose connects one port of the solenoid valve; the other port connects to the carbon canister.
The purge valve solenoid should be available at your local auto parts store.

im sure the evap system is contributing to any gas odor but my car seems to mainly be emitting the fuel smell from the tailpipes so what I was getting at is since im still in open loop at that time what are some issues that could cause it to run that rich when first started ?
Yes,
I still have the stock h-pipe. I have to take it in for the sniffer test for inspection but with the way it seems to be running rich (at least on start up) im scared of them failing it. It may in fact be running rich other times as well but I mainly notice it when I first start it up before pulling it out of the garage.
