My car check engine light came on and my car is making a pinging sound when accelerating, and not the kind from poor gas.There does not seem to be any other issues. It actually is getting better gas mileage and seems to have more power. We think possibly a vacume leak, although the sound is getting louder and more pronounced. Any help would be great..

Hi there,

I would be checking that set fault code with a scan, i would be expecting to find a faulty knock sensor, do this first.
