Low octane fuel,
Incorrect timing,
Over heating,
It sounds like probably an IAC motor (Idle Air Control motor - or valve or whatever they refer to it as).
Low octane. Either run better gas, or turn back the timiong a touch. (retard)
Check the fuel pressure......
cheap gas or your timing is out of wack put hi test gas in first to see if that takes the ping a way
chemicals and urea and ammonia
the gears have to readjust from the stop position. It is also possible that you have a broken motor mount and the car shakes when you hit the gas because the motor shifts position when the torque increases.
Your timing is off. Buy a timing light.
Answer There is no mistaking the sound a Diesel motor makes in comparision to a gas motor. If you listen to the motor and still don't know, go look at the tail pipe. On a car or truck motor the tail pipe is about 1 inch in diameter, but on a Diesel motor the tail pipe is about 2 inches around. Gas motors run quiet, on the other hand Diesel motors sound loud and clickety clank. Hope you understand. If not go to any gas station they will tell you what motor you have.
No ... the inside of a ping pong ball is filled with air. Click on the 'Inside of a Ping Pong Ball' link below to learn more.
they have the chemical boluline gas inside
acceleration = force / mass
check for air leaks from the intake tube to the motor
