Default 1998 Pontiac Firebird

We have a 1998 Pontiac Firebird that is missing. When we put a code tester on it it shows "Random miss fires" we have code tested it 4 times with the same reading. We have replaced all the spark plugs and all the wires twice, once using the cheep stuff and the second time the exact products that were original factory parts. Any suggestions, I think the next thing for us is to replace all the coil packs to see if that helps. Anyone have answers?

This is probably not the best section for this. You would get a better response if it was in the Maintenance section. Maybe the mods can move it for you?

Just an fyi, a random misfire can be cause by a spark plug, wire, coil, injector or the valve could be gummed up.
