What is the exact code number? That will indicate which cylinder is causing the misfire. Code 300 is random cylinder misfire. Code 301 is cylinder number 1 misfire.

Spark plugs and wires are the most likely suspects, but on high-mileage GM products injectors are common too. If you suspect an injector, swap two of them and see if the misfire moves to the other cylinder.
