Engine Ping

nis350 · 05-22-2016, 01:58 AM

This is my wife's car and it is also an 09 like yours. She said the same about being embarrassed getting that engine pings.

This problem started at about 55 to 60k miles and the car is completely stock.

bad/lazy O2 sensors (pre-cat) can certainly cause a lean condition, but why only occur under 'off idle' situation?

I hope you will find a solution....

Im also thinking it has something to do with the O2 sensor intermittently working to cause the off idle lean condition.

I to got not cel and will when I get around to it replace the O2's to see it that will make it go away.

The runs fine but like you know it's just annoying to be pulling from a stop to be pinging like your driving off in the wrong gear.
