Once were going approx 70mph giving it gas to maintain speed it shimmya almost likevery it feels if a tire is losing its tread. But when you let off the gas it goes back to normal. Just wonder if it sounds like maybe O2 sensor? My rear end going out?

Are you getting a vibration? If so, do you feel it in the steering or more in the seat and floor? If not a vibration, has the check engine light come on?

Yes there is vibration in the steering and yes the check engine light has been on. We left it running a couple of weeks ago on a hot day and if the air conditioner is running while in town driving then the car will overheat but you can use the air conditioner fine as long as you're on the open road and then this new problem with the vibration came about after that. Don't know if that matters or if they're related but figured I'd give you some background. Thanks

If the engine doesn't overheat on the highway, but does in town, chances are the cooling fans are not turning on to cool the engine. At highway speeds, there is a lot of air flow because you are moving. In town stop and go traffic, there is little air flow through the radiator which requires the fans to turn on to cool the engine.

As far as the vibration, since you feel it more so in the steering, that tells me there is an issue with the front tires or a steering component. The first things to check is the tires themselves. Make sure there are no shifted belts or uneven wear on the tire. If that looks good, I would recommend trying this. Rotate the tires to see if the vibration changes. If it does, then either you have a tire balance issue or a bent rim. If the problem remains the same, check steering components and alignment.

NOTE: If the only time you feel the vibration is when the brakes are applied, check brake rotors to see if they are warped.

Let me know.
