Basically, I've been having a lot of problems. Current problem...the car feels like I have 4 flat tires. Could this be shocks or suspension. I am not a mechanic and need help. also. does the air sensor and transmission body valve go hand in hand. i had to have replaced within 2 weeks of one other.

Welcome!

How about the tires? What condition are they in? Perhaps new tires are in order?

Also, can you provide more details. You say "drives like a truck". Do you mean that the steering is not precise? Did this happen suddenly, or did it come on slowly?

I have new tires. The change was sudden. I can feel every bump on the road. The ride is ruff. I am scared to drive the car. What are some of the signs of needing to fix the suspension/shocks on a 97' E320.

Do you anything about air sensor and transmission body valve. are they related?

Can you recommend a national car repair chain that can repair mercedes. In two months I have spent over $2500 on repairs from front brakes rotors, air sensor, and transmission body valve.

Regarding your search for a good repair shop, I suggest you look in 'Good MB Shops' in the General Discussion area on the MercedesShop home page. Or if you post your location there is a good chance someone can make a recomendation.

First, are the tires over-inflated? The sticker under the fuel door will tell you the corrrect pressure.

Then, has it gotten really cold? Cold weather can stiffen up the shocks, making the ride seem tighter. Water on/in the shocks can freeze, and make the ride quite stiff. Worn-out shocks usually make the ride seem more floaty and sloppy, not rougher.

No. The Mass Air Flow sensor and transmission valve body are unrelated.

In fact, Mercedes-Benz has a chain. They are called dealerships, and they are national...

Perhaps last, perhaps first. Ensure that your front spring perches are good.

Not am not seeking a mercedes benz dealership. As much as I've paid on my car I SHOULD OWN THE DEALERSHIP...

THANKS FOR ALL THE REPLIES. THE TIRES ARE NEW. I NOTICED THAT MY FRAME IS ALMOST TOUCHING MY FRONT DRIVER TIRE. SO I GUESS IT IS THE SUSPENSION/SHOCKS, OR SOMETHING RELATED.
