So the other day coming home from work my check engine light came on.
I got home and hooked my code scanner and it had a P0175 code with a pending P0172.
Odd I thought, I have not noticed any driveability issues or other problems.
Got home, popped the hood, took a quick look at everything and noticed no visible problems (vacuum hoses fine, all wire connected etc).
I had just filled up so I thought maybe it had something to do with that. I cleared the codes and went on my way.
I knew it had something to do with running rich, and figured I would see if it came back.

Drove for another few days, no light.
I am due for inspection this month so I wanted to see if the O2 and Cat's were ready (the O2 sensors were, cat's were not)
While hooked up I saw the P0172 pending again.
So I started looking around deeper and still found nothing.
When I get to the air filter, I found this:





Well that's not right.

Went and got another filter and cleand the MAF (just in case, it looked clean).
Hopefully that is all it was.
Filter has been on for ~15,000 miles/3 years. Don't remember what brand it was, but was one I got off e-bay.

 

That use to happen quite a bit way back when blup. Back then there was just one air filter that lost it's cone like that, that was the Fram. Yea, they started all that but I have to say, I haven't seen it happen again for quite awhile until now.

So I guess someone else is selling that cheap filter again or one like it...jeezzzz.


Crap! 15,000 miles! I'd be upset, how is the truck running? That's a little worse than running a K&N.

 

Yeah, I was being cheap when I got this, the truck was not even running at the time and I just wanted something else in there besides the dirty nasty one that was in it, so for $7, why not. It lasted a while, and was something I planned on changing eventually...

I have driven 150 miles and not even a pending code. That was all it was. Wish all codes were that easy to fix.
