Thats simple,due to experience..it's your cv joints,,worn out..but take notice, it can be from regular wear and tear,or due to soft motor mounts,creating undue stress on the inner joints.The motor actually twists to far and creates damage to the inner cv joint.I replaced top(driver's side mount)and the bottom mount.Installed new Cv's,,result is aok. Note:Most say the motor mounts are only good for 4-5 years,before replacement.
I had the exact same problem with my '92 Grand Voyager, a bad shake and wobble in the front end only when accelerating and was especially noticeable around 35-45 mph. I finally found a mechanic who knew exactly what the problem was. My c.v. joints were fine, the problem really was the motor mounts. They were badly worn (182,000 miles) and one of the mounting bolts was actually broken. He explained that the extra play in the motor mounts causes the c.v. joints to "bind-up" under acceleration. I'm no mechanic, but I do know that this fixed the problem. You will probably have to replace all three mounts to remedy the wobble.
It sounds like u need to replace the thermostat. At slower speeds the air flow through the radiator is minimal, but at higher speeds the air cools the radiator more. This only happens if the thermostat is not keeping the water in the engine block long enough.
My minivan was doing something very similar. Does the vibration/wobble stop when you let off the accelerator? Try coasting down a hill without touching the gas pedal; if the vibration stops when you let off and then starts again when you push on the gas pedal there's a good chance the vehicle has worn-out motor mounts. I was skeptical when my mechanic told me this, but after he replaced the mounts on my '92 Voyager 3.3 liter there was a huge improvement to the wobble/vibration that I had.
4,163 were made.
NASA can predict the speeds of the two Voyager craft very accurately. The main problem is defining where the "end" of the solar system is.
There are two 'relays' under the hood. Check the relay cover (driver's side toward the firewall) to see which fuses and relays are which. As I said there are two..one for the windsheild wipers, another for the hi/low wiper speeds. Check these first by replacing one or both. Should cost app $10 each.
it speeds up and speeds down
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds
Analog can reach higher speeds.

By large distances between particles that are moving at high speeds
It is possible that the car has a governer on it which will stop the car from going faster than a preset speed. also a 98 Plymouth neon which i suspect has a 2.0 engine lacks high horsepower which is needed to make a car faster at higher speeds
