It bounces when it goes down the highway - 1995 Buick Riviera

Car bottom out, feel every thing, lots of bounce in car, sometimes u can see fluid leaking from strut

Fan clutch most likely went bad

That would be something a person needs to experience first hand.
Does it feel like it coule be bad shocks and the rear is bouncing. That might have also caused the tires to go a little out of round.
Or is it a vibration? Maybe the tires just need to be balanced. Out of balance tires/wheels will vibrate to a certain speed (say 55-65ish) and smooth out as the speed gets higher.

mine does the same thing... check the relay behind the glovebox.

have your tps check, sometimes cleaning the throttle helps

I have a 2000 chevy impala when I'm on the highway the temp gauge goes down, but in town stop and go traffic it goes up. what is wrong? what is normal?

That vehicle has two coolant temp sensors on it, both are on the passengers side of the end of the head, where the thermostat housing is. One has a two wire plug, this one tells your fans to come on the other is one single pin, this one is for your temp gauge. This sensor works off resistance, the higher the resistance the higher the gauge in the car goes. This sensor has probably grounded out and pegged your gauge in the car. Replace that sensor and you should be good to good, not too expensive either. Good luck.

I would open the hood and attempt to move headlight assy. Note any abnoral movement and inspect. Possibly loose bolts or broken tabs

i was having the same issue with oil pressure and i only had 55K on mine, i have since changed the cat and the exhaust manifold and the problem went away? might be a coiencedance but it makes since thinking like an exhaust brake would work
