G6 has a miss or sputters at a stop.Had fuel line cleaned & tune up with spark plugs replaced.Still happening.Very frustrating.
Car just stopped running. Sat for awhile and started again running rough. Stopped waited then started right up.

Started missing when you come to stop at a signal light. Very annoying. Took the auto repair shop.Hooked up too computer but not showing anything wrong. Did tuneup, didn't work. Next changed the throttle body. That didn't work. Checked gas tank, had some sludge and a little water. So took it off an cleaned and also cleaned the fuel lines. That still didn't work. Finally someone came from a dealership to the shop. Said he thinks he knows what it is. Had some kind of computer system from the dealership. Hooked it up. Showing it had a bad coil wire. Computer knows which one. So only had that one replaced for now. Guess what, it's working right now. So for now I very pleased.

All of these people with this same problem, clearly it is something general motors is doing wrong along with the other things(recalls) but you think they will fix it? No, why? because they are rich people who DONT CARE about anything except making millions. They make their products to fail, so that you have to spend money to fix it and they continue to make money!!! So here i am stuck with a 14,000 dollar car that i had for 1 week before it started acting up, and needs a new motor because it cost more to fix the piston! 14,000 dollars for a care that needs a new motor!!! My advice, NEVER buy from them!!! Wish i never got this stupid car!!!!

my g6 also had a misfire problem on cylinder 1 and 3 with the 3.6v6 VVT engine, hey changed spark plugs and the ignition caps. i actually found the problem online. its not a 'G6" problem its a cadillac problem its there engine and its due to poor timing chains. if you let your oil change go past the 5000km mark even though ur display says 65% oil life remaining the chains expand with heat and throw the engine timing off. once it gets it half inch out ur engine light will come on. there are 3 chains in that engine. get it done before the crank gets ripped up

My car will shake mostly at redlights or stop signs but the engine light did not come on. The engine light came on briefly and went off and I had it towed to the dealer. They told me that there was antifreeze in my oil and oil in my antifreeze, there was a blown head gasket and he named some other things that was wrong. they told me it will be approxiamtely $5,500 without tax and labor. I had my car towed to a garage. Just waiting for them to give me a price. Hopefully, it will not be as high as the dealer.

Car has a miss started out randomly but now getting more common
2007 Pontiac G6 - 3.5L V6 150,000 mi,
06 G6 GT. 150k miles. CEL pulled random misfire code. Rather than troubleshoot all that it could be, decided to pay the diagnostic fee to pinpoint what it was, at GM. Was told that two spark plugs were bad. Replaced all the plugs. Within 5 minutes of driving, CEL again, random misfire. Dropped it back off with GM. A week later, diagnosed with low compression in one cylinder, possibly resulting in a misfire. Not amused. Car has been one problem after another. 4 recalls in all. Replaced multiple less than adequate OEM parts on the car. Steering rack still clunks. Now, needs a motor? Will not buy another GM.

2007 Pontiac G6 - 2.4L 4 Cylinder 100,000 mi,
engine code reader keeps saying multiple random misfire cylinder one. 2 days ago i did allot of work to it. i replaced the plugs all 4 coils the mass air flow sensor the upstream and downstream 02 sensors for starters. unrelated to that 1 day ago i also replaced both front wheel hubs all 4 calipers, rotors, & pads as well as oil change, air filter and transmission filter change. the car at the time of all the work has close to 200,000 miles now but I'm getting really tired of the check engine light for this same reason when it should be fixed by now. Any help on what to do or what it could be would be much appreciated.
