I cant figure it out. I changed everything.
Fuel filter
Spark plugs
Oil/filter
Air Filter
Cleaned everything(sensors)
Distrubuter Cap/Rotor
Im thinking its my o2 sensor.. What would be symptoms of a bad o2 sensor?

I dont know what my fuel pressure is right now. Um, it only surges/stall when it is only ar operating temp. I dont know the vacuum right either.

yah, i'd start with checking the timing. stock setting was around 10*, 14* is a good advance for a stock motor
helps greatly in situations like yours

RE: Hesitation at WOT off of idle, only when at operating temp
Hah, mine sometimes hesitates when the fuel level is really low...lack of fuel pressure i guess... maybe thats your problem. It also did that when i had a poorly fitting set of spark plug wires, the wire was taut against the block and must have been grounding itself...I have no idea really, but the stock wires fixed the problem.
