When the weather turns cool, my car doesn’t run as smooth.

Slight rumbling here and there, which was experienced in the past as well.

Occurs when changing between park, drive and reverse and when idling; all intermittent.

Acceleration doesn’t seem as smooth at times either.

Not present when warm out.

Definitely complained of same under warranty, but fell on deaf ears.

Any thoughts?

Thanks.
