How do you stop rough idling and sputtering on a 92 Pontiac firebird?
Could be a number of things. Start by performing any maintenance items that are due and listed in you owner's manual. If you have not done so, replace all vacuum hoses, including the brake booster hose. Check the booster for a cracked or leaking diaphragm. Replace the hoses one at a time to avoid getting confused. If it idles rough but runs good under acceleration, then a vacuum leak is probable.

An air conditioning compressor places a heavy load on an engine, especially when the engine is idling. If the engine is running rough at idle with the a/c on, try changing the spark plugs, air filter element, and the oil and oil filter. If your car has a four cylinder engine, you may have to turn the idle speed up slightly. Shift the transmission into 'Neutral' while waiting at stoplights to reduce the load on…
It might be the idle air control valve. It is about a $40.00 part. It is a cylinder shaped unit bolted down with 2 bolts with 2 wires attached, located between the air intake and the throttle body. it could also be just a simple tune up. try replacing the plugs and coil packs/ wires. (i forgot what ford used then, i believe there coil packs.)
