Possible engine knock from using too low a grade of gasoline. If you have a Turbo, VW highly recommends using at least 91 Octane fuel.
Have the motor mounts and trans mounts check as these will thump also upon acceleration as your motor and trans will jump or twist slightly when accelerating. These are basically supports and cushions for your motor and trans. When they go bad there is nothing to really keep them from twisting or moving. Just a possibility.
Gasoline pedal/air intake pedal
No, any smoke is coming from the engine.No, any smoke is coming from the engine.
The reason why it is vibrating is cause of the Engine Mounts. You have to get the Engine Mounting changed ! cheers.

My 99 sonoma had a knock and it was a wrist pin in the engine, my 99 jimmy fuel injection leaked gas in the engine oil and caused the main bearings to fail because of lack of proper lubrication.
The 1995 Monte Carlo could have a vacuum leak. An engine vacuum leak can make the car idle up and accelerate.
Had a Jeep in the shop here with that problem last week and it turned out to be low fuel pressure. Try running a fuel pressure test. The Jeep would idle ok but when you tried to accelerate the engine would stall.
A dirty air filter will cause your automobile to not properly accelerate. A dirty fuel filter will also cause your automobile to not properly accelerate.
Your vehicle has an oil leak somewhere..............
It can cause a rough idle. And it will also cause the engine to die when coming to a stop at times.
It is an engine misfire. Don't accelerate too fast or brake too fast. Get your car into the shop as soon as you can because it can/will cause damage to your catalytic converter.
The more you push on the accelerator the more you increase the fuel/air mixture to the engine which will cause the engine to turn more RPMs, thus propelling the vehicle at a faster speed.
Problem with the transmission. You need to have the transmission computer checked for codes to know a possible cause.
A very plugged up fuel filter.
Fuel pump going out throttle body needs replaced air fuel mixture not set right.
An unbalanced force will cause an object to accelerate.
Crack in intake or exhust, or belt glazing- Check all the intake and exhust bolts.
If it only happens when you accelerate the most likely cause is an axle.
