I have a 98 wagon that I just picked up. It's got 165k on the clock. I'm noticing that it misses a bit when first started (maybe first 1 minute while driving or maybe a little more if just idling). Then it clears up.

Any idea what could cause this?

I would say this has something to do with your bad mpg's too. i would try to clean the maf sensor and see if that does anything for you. Do you have any codes?

I had some codes. I had coolant leaking out of the reservoir (replaced it) and that may have set one of them. Here are the codes that came up. I cleared them and they haven't come back up in around 100 miles or so of driving so far:

P0402 Exhaust Gas Recirculation Flow Excessive Detected
P0401 Exhaust Gas Recirculation Flow Insufficient Detected
P0455 Evaporative Emission Control System Leak Detected (gross leak)
P0117 Engine Coolant Temperature Circuit Low Input

As far as I know the car hasn't been on dirt roads. I purchased it in a decent size city.
