Take it back to who tuned it up, ask them if they cleaned the throttle body. Ask then if they gapped the plugs before they put them in. Did they put the sparkplug wires back on tight? Take it back and tell them you are not happy with their work and don't take it from them until it is right. Ask for a copy of EVERYTHING they did in their tune up. egr valve or eps sen

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.
