squigs1 Posted January 19, 2010 Report Share Posted January 19, 2010 Here is my issue. I just bought a 2006 CTS 2.8 6cyl. The car drives and handles great. The problem I have is when I am trying to drive at a steady speed my rpm's jump between 200-300 steadily back and forth. It only happens when im trying to go at a steady speed or am in cruise. It is very annoying. I called the dealer where I got it from, there tech told me it is normal and thats how it holds its speed in place. Is this true? I dont remember any other car ive had do this back and forth rpm fluctuation. Getting kinda sea sick when I drive. THANKS FOR HELP, STEVE Link to comment Share on other sites More sharing options...
Bruce Nunnally Posted January 19, 2010 Report Share Posted January 19, 2010 Does it feel like the engine is surging, or perhaps the transmission torque converter is engaging/disengaging improperly (at steady speed)?

squigs1 Posted January 19, 2010 Author Report Share Posted January 19, 2010 Does it feel like the engine is surging, or perhaps the transmission torque converter is engaging/disengaging improperly (at steady speed)? It does feel like a small surge. Its just a very constant surge than backs off and surges again. only a couple hundred rpms Link to comment Share on other sites More sharing options...

tgiesbrecht Posted April 19, 2011 Report Share Posted April 19, 2011 So glad to hear that I am not alone. My 2006 CTS 2.8litre has EXACTLY that same issue. When at a steady speed the engine seems to surge back and forth about 200-300 rpm. I've had itin the shop and they fixed a couple of codes that the transmission indicated was in error. But I've still got the problem. The dealership have said this is the way they normally feel. I've had a number of cars in my lifetime and this is the first time I've experienced something like this. It is subtle but it drives me crazy... for a Caddy I would expect a much smoother ride. THis car idles almost silently... it has only 28000 kms on it. If you find out what the cause of this is I would sure appreciate hearing about it ... love this car in every other way but must get to the bottom of this!
