CHECK FOR VACCUM LEAKS , BROKEN HOSES , OR DISCONNECTED HOSES ON THE MANIFOLD OR CARBURETTOR .EVEN A DIRTY CAB CAN CAUSE THIS SYMPTOM .

I would start with the IAC (Idle Air Control) valve. The IAC valve usually, USUALLY, trips the Check Engine Light, but, sometimes may not.

Aside from that, it could be other issues: spark plugs, ignition wires, distributor components/assembly, etc.

BTW, is the Check Engine Light on?

Based on the information provided, it sounds like a bad TPS (Throttle Position Sensor). The TPS controls your idling speed under all conditions. When a TPS goes bad, you will usually notice the vehicle will idle when the engine is cold but once warm or with the AC on, it will sputter or stall.

sounds like a vacuum leak around the throttle body. i would try replacing it with an identical used one.

remove two bolts holding disc caliper to strut assembly. remove discpads.use a g-clamp to push brake pistons back so that when you insert new pads the caliper will easily fit over disc.tighten bolts securely

I've had similiar issues with a different vehicle. I had to purchase new plugs, rotor, and distributor/spark plug wires. I was running on three cylinders verses four. I did not notice until I was going up hills, where it required more power. If you have a tachometer, keep an eye on it. If it is running slower than it should that could be an indication that there is a problem with the wiring. (probably should be doing about 2500 rpm)

I had a Hyundai that did just the opposite. It would peg the tach to 3,000 rpm well before it was time to shift. Ended up being an ignition coil went bad, which takes the place of the distributer. I replaced the ignition coil and now the engine doesn't have to run as high.
