Ok... So, if i baby the car... No more than 1/4
throttle, everything is fine. However as soon
as i give it any more than that... Passing,
hills, etc. It studders and goes into limp
mode... Also when i crest the top of a hill...
Like when you get that zero G feeling in your
stomach... Instant limp mode
any check engine light? MOST, auto parts and dealers will tell you what the code is so you can trouble shoot from there... try to keep the rig running when the light is on, otherwise the computer will store the active code and it's harder to trouble shoot.
My 2017 CTS rides hard how can I tell if it is going in to tour mode
