99 Malibu response is running pretty rich (smells very fumey) and the ignition beep that turns on when you turn the key continues to beep when running. I'm assuming those two issues are unrelated but I've heard the beeping can possibly be oil pressure.
any advice for addressing/checking those two issues would be appreciated!

I would check the idle control valve on the engine intake. It could be all gummed up. The intake manifold and plenum gets a lot of oil overtime from the breathers.

I thought a friend of mine was insane when he bought an X80 back in 2007 for $110k. Now you can’t get a ProStar for that.

All good advice. Next cold start key up 2 or 3 times before starting and see if that changes anything.

The suggestions from Justgary sound like the best thing to check.
The Throttle Position Sensor (TPS) only richens, or leans, the fuel when the throttle is moved (especially when it is moved quickly), and should not impact cold starting. The Engine Coolant Temperature (ECT) sensor does affect starting by richening fuel when the engine is cold, and leaning fuel when the engine is hot. MEFI4 ECT value default is -49 degrees F when it is disconnected which would make warm/hot starting more difficult (the opposite of your issue), so that is also not likely the problem.
