Having a problem during acceleration with my G6. When I'm driving it normally and I go to gently accelerate while running below 2000 RPM, the engine begins to sputter like it is wanting to die, then will suddenly accelerate as if I had floored it. This happens I would say about 90% of the time going up hills, but can also happen along level road too. The only thing that seems to keep it from happening a lot is adding fuel injector cleaner (Lucas brand), but it will still do it off and on with this. All the while it has been doing this for the last 8 months, it has never once given me any sort of code. I took it into the dealership but they just said it was carbon buildup on the sensors and were going to charge me over 300 dollars to clean it up. I have heard it might be anything from bad spark plugs to the catalytic converter, but I don't have enough money to play guessing games with it. If anyone has any information about this please help!

LOL I've had this problem for 25000 miles! I lost track of how many places I brought this car to have that problem fixed! I have no choice but to let off or give it more gas, then it comes into it. WTF? I feel your pain! My 05 G6 ran fine! By the way, there is no recall on this problem that I have found , but THERE SHOULD BE!!!!!!!!!!!!!!!
How do you get information on the recall? I have the same problem.
Im having the same problem with mine, any idea what it is? Ive already replaced my 02 sensors and it still wont accelerate over 5 mph.
