Is the check engine light on? Is the temperature normal? Any work was done on the engine or around? How did you check your air flow meter? The air flow meter have 2 little hot wires where the air is passing by. These wires need to be extra clean or the they will give your pcm wrong info. Stephane

Check your exhaust. Blocked or partially blocked cats will cause this.

could the engine be running too lean ?

If you are getting a ping every one second, you could be hearing something else entirely different, like a miss fire on one cylinder.
