Maybe some of ur sparkplugs are not working causing the spark to ignite the fuel but idk why it would be doing that maybe an injector is bad
My guess would be wheel balance.
I would check your tires they could be out of balance. or a tire could be bad .

pulsating effect The Abs equipped cars do this naturally older cars with abs you will notice it more so than newer models.. If it just started occurring there may be a problem in the braking system. if it feels as if you are going over rumble strips (without the noise) when you brake first suspect would be a warped rotor.
Check your cooling fan motor. If it is no good when it goes on it will make a pulsating sound.
Most likely its the throttle cable, if not I would check the linkage between the gas pedal and the throttle body.
If the idle is set too high, and you have an automatic transmission, this will happen. A sticking throttle cable or rod can also do this.
depends is it automatic or manual? if its automatic its more than likely that your transmission isn't shifting into first gear
AnswerUsually a pulsating brake pedal is an indication of a warped rotor. When you replaced the rotors did you torque the lug nuts to the proper specs, (80 ft lbs)? If not then you are warping them each time. Also make sure you tighten in a criss cross pattern. Of course you need to check each and every rotor for trueness. Also a warped wheel can cause this. Check all your wheels for a bent condition.If your brake pedal is pulsating. You might have a out of round rear brake drum. When your front rotors are warped you will feel it in your steering wheel. Try this test. lightly rest your foot on the brake pedal, with your foot resting on the pedal slowly apply your E brake. ( your E brake only works your rear brakes) If your brake pedal pulsates the problem is in the rear brakes.
I would say no. There is no reason to expect it to accelerate.
Check for warped front rotors. under slight brake application it may not shake. But under hard braking such as getting off an offramp the truck will shake and the brake pedal may pulsate slightly. Chances are real good this is your problem.
The phrase is "Audi 5000," referring to the automobile, which experienced "Unintended acceleration." It would accelerate from a standstill with no touching of the gas pedal. Thus, "I'm Audi 5000" means to leave abruptly.
