Hey guys/gals I am new on the forum. My wife drives a 2010 G6 GT with the 3.5L V6, 4 door. I have been a Pontiac fanatic as I have owned about 4 Trans Am's, own a 2000 WS6 currently with a LS6 I built for it pushing around 480hp to the tires and 454 tq as well. So on that note I understand how engines work and I understand sensors can be a nightmare. The problem I have with the G6 is when I drive it under normal acceleration between 1500-2000 rpm it skips and jumps around the rpm range until it reaches anything over 3k then it clears up for the most part. I thought maybe the injectors could have been clogged from bad gas or something but I have run Sea Foam at full strength a few times because I it seems to be the best I know about when it comes to cleaning out fuel systems. Anyway has anyone had an issue with their 2010 similar to this? I have not checked the plugs yet but I wouldn't think with 32k miles on the car they would be bad. Thanks in advance for the help. I use LS1TECH for my TA's tech issues so I hope this forum can do the same for the G6 =)

Any stored codes? Even if check engine light is not on there could be codes. Start there. There are so many things that could be causing this hick-up. I am currently dealing with one caused by the electronic throttle body.

I was unaware it could be throwing codes without actually setting off the SES light. I will start there I guess, thanks.

I have checked everything I can think of, even decided to bite the bullet and take it to the stealership to check for any stored codes but all I found was less money in my wallet. Has anyone else had any issues like this? It specifically jumps rpms between 1500 and 2000 rpm while accelerating at a normal pace. It is my wifes car and I don't drive it every day but when I do it drives me insane! Any ideas would be very helpful, thanks.
