Sometimes when the Turbo spools up I hear a pinging... this normally happens under heavy accel when the turbo needs to build up the boost. Im hoping its normal that it will occasionally do this..

Im really hope it isnt what I think it is...

 

well ping doesnt happen in your turbo...

you running high enough octane fuel? Maybe you got a bad tank of gas or something... who knows.

 

The last time that happened was when a O2 sensor went bad... because of my K&N Filter. Did I learn from my mistake... no, its back in there. I put that thing out in the sun for like 6 minutes to let it dry... I guess I have the O2 sensor to look forward to in the future.

When I say PING... I dont really mean a ping... it sounds like the ball bearing in a spray paint can being shook ( if you can imagine). It doesnt happen often but Im just wondering... ******* K&N Filter. I think Im going to take that **** off once and for all...

 

Sounds like lean condition.

Could be oxygen sensor or MAF or clogged fuel injector.

I'm waiting for my MAF to come from ECS [:@]
