When it idles it goes to like 100-200 rpm and when i hit the ac on it will go up to like 900 rpm

You need to adjust your idler, 5sfe should idle at 700-900RPMs. You can adjust it by tweaking your cable that is attached to the throttle body. The reason why it's studdering is because it's about to stall out. Cars can't idle that low not even a ****ing prius haha.
Second, the reason why your idle goes up when you turn the A/C on is because the A/C compressor is run of your drive belts. It uses engine power to run the A/C, so if there is a larger load on the engine, it will increase the RPMs to compensated. In other words it uses up all the Horsepower when you idle so it increases the idle to maintain that same range of Horsepower make sense? This is why races shut their A/C's off because it uses up some Horsepower.
could be your iscv, idle speed control valve.
get a good thorough throttle cleaning, include the iscv on the cleaning.
hth
I have the similar problem so after a BIG search and many hours in services the reasons for this can be:
-some of the fuel system sensors is dead (4 of them)
-need to clean the throttle body very nice!
-vacum leak
good luck
thanks guys! hey cyprus i have the same muffler as you, the people who welding it up put mine kind cricked and pointed downwards, piss me off
clean out your throttle body and IAC valve really well(the iac valvle is under the throttle body....) its best to take it off the engine and completely apart to do this.
