Been having issue with stumbling on acceleration and fluttering at highway speeds. Changed a bunch of things but the problem persisted. Took it to the dealer for a diagnostic and they said it didn't throw any codes for them when they drove it but that they found two bad motor mounts and the transmission mount was bad as well.

Anyone ever experience something like that? Bad motor mounts causing hesitation/stumbling on your Blazer?

Since you already have an on-going thread concerning your hesitation problem, lets keep the discussion there.
