    I have the same problem. I changed all plugs and wires with AC Delco plugs and wires (recomended by GM Mechanic). Solved it for two weeks. For some reson it seems to go away when its dry out side, when its humid or rains it comes back. Next change will be coil.

My 2003 Pontiac Grand Am GT has a flashing and sometimes a Solid SES light and runs rough


Usually with the newer vehicles when it starts to run rough or idle poorly it's time for a tune up, that will also make the check engine light come on on some vehicles, it needing an oil change can also cause the light

I would try replacing the fuel injector ,now the mechanical code,could be a valve spring, lifter ,or valve problem,but try the injector first.

2001 Pontiac Montana - what is a misfire #5?


Without your actual trouble code, I am assuming that you are have a misfire on cylinder # 5. The computer cannot really tell what is causing the misfire only that cyl 5 is not putting out full power. If it misfires when cold then smooths out as it warms up, I would say it is probably an injector that is sticky, as it warms up it starts working properly.
