do I just have problems driving a stick? and other concerns

I mean I've been driving them since my 94 SC2 in Jan. of 94 but with my 98
SL2 if I'm running the AC and take off from a dead stop it seems like the
car wants to lurch forward and die. I've had this "problem" in various
temps and weather in the past though sometimes when the AC is off. I'm
really not sure if I should be looking at a mechanical issue or if it's just
me lol. I do notice some rough idling once in a while though and I thought
maybe it might be oxygen sensors or EGR valve. The engine is on a 98 SL2
with about 120,000 miles. Not using more than a quart of oil per 3,000
which is well within specs (usually 2/3rds to 3/4's). I have replaced the
ignition from the coils to plugs all at one time because the stock coils
were shot (3 of 4 terminals corroding). Have also upgraded to a hotshot
intake and as of Wednesday the HKS exhaust kit. Haven't noticed any
problems so far WITHOUT the AC on recently but the "problem" is still there
when it's on. My guess is I'm just not giving enough gas when the AC is on
since I hardly use it and am just likely not used to really driving with it
on. That doesn't explain why the car would do that during much cooler
weather (40's) though unless it has something to do with not being warmed up
enough. Anyway, any insight you guys can give would be appreciated. Should
I just take it in to Saturn and tell them what I'm noticing and have them
hook it up for diags to make sure nothing is wrong? After being unemployed
since last November I just got a new job starting Monday but it's an 84 mile
a day round trip (funny, my last job was similar which explains the 120K
miles) so I want to make sure nothing is really wrong here that could turn
into something major. Thanks guys.
