Hello,
I have a 2010 CX-9 3.7L engine
I have had past issues when accelerating to about the 45-50 MPH range and the vehicle would "shudder". I had the CV joints replaced and that cured some of the issue.
Now when you slowly accelerate through 30-40 MPH you will feel a "stumble" as if you were driving across speed bumps, It will not happen if you accelerate very fast though. I have changed plugs and coil packs, and their is no CEL on.
I asked my wife to put 93 fuel in and she said that it slightly felt better but it was still present. Not sure if it a motor, transmission, or drive train issue??
Any help would be greatly appreciated
Thank you
