I have replaced the coils and plugs. I am getting the P0304 code for cylinder 4 misfire. Car does not get hot nor does it lose coolant. I have run the compression and only 4 has slightly less compression. Some times the check engine would come on and it would jerk slightly when putting in gear and again jerk when shifting from 1st to 2nd gear. Sometimes it would flash CEL and I would find a fouled spark plug. The last two months I have replaced the plug again in cylinder 2 then 4. Not sure... 2007 G6 2.4 Ecotech slight miss and jerking into gears ..read more

On a 2008 GT convertible 3.9, I had to open up the top to windshield area while working on a "top not secure" error message, and I was wondering what is this piece on the driver's side trim? It is electrical as it has wiring connected to it. Also, what is this black thing that sits above the dome lights and top control switch? It seems to be floating in a rubeer mount. And what is this antenna for? There is the regular antenna on the left rear quarter panel, so why would there be another... What are these things ..read more

What is the current hotness for headlight assemblies? I would prefer an upgraded bulb, light LED or HID, but the standard halogen would be okay. I like the look of the black plastic, but it seems most of those come with smoked plastic are OR only. Extra points for simple, simple installation. Should I replace the connectors at the same time? I'm not having any trouble with them, but reading the posts, it seems like that is only a matter of time ..read more

I'm getting a CEL and "low coolant error" on the radio on my 2005. Coolant level is full (it actually was a little low but there was no error - it was after I topped off the coolant that the low coolant error appeared). Reservoir is full and car runs at normal temp. The thermostat in this car was replaced less than 2,000 miles ago. I hooked up a code reader and there are no fault codes for the CEL. I tried to clear any existing faults but the CEL does not go away. Any idea what this... low coolant alert but no engine code ..read more

Hello I have an 06 G6 3.5L with 136k miles on it, and I've noticed red fluid leaking under from my front bumper under the radiator. I've been checking my coolant levels regularly since, but I haven't lost any coolant and my temps have always been good. I think it might be transmission fluid since a week ago my transmission has been slipping a bit. I'm planning on changing my transmission fluid to remedy that pretty soon. Does this sound like a transmission leak from the radiator? How... Leak under radiator ..read more
