I have an '05 CTS with 8000 miles on it. At about 5000 miles, I started to notice at highway speeds, a slight cutting out, or "missing" feeling. I don't want to use the word "surge", as it doesn't lunge, but more of a cutting out -- very slight, but an "all the time" occurrance. I thought maybe it had something to do with the a/c (compressor kicking off and on), but after running with it off for quite some time, realized that it wasn't the a/c. I took the car in for servicing and asked the dealership to see if they could figure out why it was doing this. Well, of course they couldn't feel it, and with only driving it 18 miles, I'm sure they didn't drive it long enough, or on smooth enough road to feel it. But it's there, and it is really driving me crazy. I've been watching the rpm's when it does this, and the needle does not move, so can I rule out the engine? What about the transmission? Would that cause something like this? Or perhaps the fuel pump? I'm at my wits end, and not sure whether to go to a different dealership and have them look at it. Anybody else felt anything close to this?
