Running ok day before. started next morning running rough, service engine soon light flashing indicating missfire. car has very little power
I had that problem once. when i got under half a tank of gas in the tank. What i did was i dumped one bottle of gas line deicer in the tank and i have never had it agian. you may have some water in the tank. from condasation or i have a stong feeling i got my water from the gas station. i was using the same station all the time. so i tryed another gas station and so far no more rough idleing which was caused by the water i think and i am getting better fuel milage to. i hope this helps.

I have the same problem. I was told it I have a broken rocker arm and need a new or rebuilt engine.
2002 grand am idles rough no power misfiring on2 cyl code
Just took mine in today for the same issue. 2002 with 30,000 miles on it never had a single issue ran great like always the night before next morning slow to start (crank a couple of times ( not normal) ) Drove it to dealer since I have a couple months left on extended warranty. No power had to manually downshift ( it is an automatic) and engine\tranny was hot ( did not set off dummy light but could just smell it. Will seee what they find and post back.
same problem low power misfires
You may want to start with getting new plugs and wires. That may help.
I had no power and it was running very rough. I started noticing it during steep inclines mostly, than I could not get it over 50mph. RPM were anywhere between 4-5 and it would just rev, no acceleration. The engine never got hot though, temp. gauge stayed normal through it all. My '02 has over 150,000 miles on it. I took it to the dealer for diagnostics. My catalytic converter was bad and I needed new plugs and wires.
