Question
why is my car jeking, has a hard time accelerating, and has a pinging sound to it.

Answer
Pinking is a problem with your fuel mix/ignition timing and should be repaired as soon as possible as it will cause serious engine damage.The cause could be many reasons but you should have gotten the check engine light on for this is a major problem.A likely source is the knock sensor or incorrect fuel.
