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.
