vibration in gas pedal when I slightly hit pedal.
Probably needs a throttle cable adjustment or it is binding slightly.This can certainly be felt through the gas pedal under light acceleration.
No throttle cable, this car is drive-by-wire.
I have a 2013 Equinox with 91k miles. If you use ECO mode shut if off. The idle speed will increase and the engine will run smoother. Also, driveability will improve with minimal impact to mpg. I stopped using ECO mode after the pistons, rings, and a timing chain were replaced at 42k for the oil consumption issue.
About every 30k miles I use Seafoam Top End Cleaner to clean the intake and valves.
I only use about 1/2 of the spray can at a time.
Thank you for that. I had tried that and it did nothing. I’m just concerned it could be a motor mount or CV shaft.
