A person pressing the gas pedal.
Yes, it sure can.
shaking jerking when pressing on gas
My 98 Ford Explorer eddie bauer edition as started to make this whining noise when im accelerating.. it stops when i take my foot off the gas...what is going on?
press the break and call the car company you bought it from.
Pressing on the gas pedal sends more gas to the combustion chamber for the combustion process which sends more pressure to the engine for your car to pick up speed.
Your car is making a funny noise while going downhill accept when pressing the gas because your car has all them teeth and no toothbrush! Also your car is a piece of crap and needs to be replaced with a better one. If I had to bet, I would say you are driving an american made car, more specifically, a Chevy. hahahaha chevy is the worst car company in the world!
Take a mechanic's stethoscope and listen to the car with someone pressing on the gas pedal. Then, take that and apply a Doppler effect. You will get a nice wave pattern for your listening pleasure.
May be you have a misfire?
you may have water in you gas and your injectors may be clogged.
Could be as simple as needing a tuneup with a new set of spark plugs.
