Recently purchased a K2500 7.4 L Suburban with 22000miles on it. generally perfect other than a very slight "lurch" when taking my foot off the gas at speed. I had a similar problem with a Chevy Corsica which turned out to be an oxygen sensor, but the Burb has four! Any thoughts, and no I am not expecting to smooth a ride!.
Hmmm, a failed OX sensor on any '96 or newer vehicle should set the check engine light on quickly. I doubt that is your problem.
I would check all the engine and transmission mounts as the first step. Also, driving a similar vehicle to see if what you are feeling is "normal" or not would be a good move.

Many thanks for your reply. Problem seems to have developed over the past
500 miles, and is (I think) intermitant.MotorsForum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
