Hi folks...I am new to this board. I have a 2008 Cobalt LS, 2.2L, 5-speed manual transmission, with 170,000 miles on it (mostly highway miles by the previous original owner). About a week ago I started getting an occasional stumble while driving. At first it was just on the interstate with a warm engine and just cruising along, then it stated doing it even when cold and during acceleration too. Sometimes it just does it once...other times it does it 3-4 times within a minute.
There are no engine codes being thrown. The engine runs and sounds fine otherwise. Transmission is manual so I know its not a tranny issue. My gut tells me its a misfire, but I'd think there would be a code thrown for that?? I suppose other option could be a loose or corroded connector.
Any ideas here? Should I go ahead and change the plugs first and see if that helps? I hate throwing money at something I can't nail down.
Thanks for any help.
