Hard starting and poor idle in hot weather

[IhaveNoPantsOn]

So, with the past couple days of 80+ degree weather, I am starting to remember one of the big PITA issues I had that made me take the GP off the road for a while. In hot temps like this, it is nearly impossible to get my car to start on the first try. Put the gas pedal to the floor atleast once, start it, rev it a few times to bring RPMs up, just to get it to idle. After driving it a little bit, it seems to drive and idle ok. As soon as I shut it off, and try to restart it, same exact thing. I don't dare turn on the AC, or it stalls instantly. Someone said it could be the choke not opening, but it seems to be fine. Any other suggestions on what to test, or look for? Thanks.

idle compensation motor working?

Yeah, it is, because once the car gets running good, I can put the AC on, no problem.
Even tonight, with only 65 degree weather, it took me 3 or 4 tries to start it. once it was running, I had to keep it revving a little, so it wouldn't stall. After only a few minutes of driving, it was running fine. Also, on cooler days, it starts and runs great, until it warms up, then instantly feels like It's misfiring or something. The exhaust tone has a definite stutter to it, and very poor throttle response and power. I have had this issue for as long as I have had the car, almost 4 years. I would really like to figure out WTF is wrong. Any help would be awesome. Thanks again.
