P0171 read, bank 1 system too lean. I relate this too an O2 sensor but I could be wrong.

P0507 Don't know what this is.

Has anyone had these codes and what turned out to be the issue.

I have had the P0507 code. The idle would hang, more than usual. I could also put it in third gear and coast @ 1,500 RPM without touching the gas (also on level ground). Any ideas?

I can't believe the lack of traffic on this site

Anyways, I just ordered a new BSH PCV kit with Catch Can. I 'm thinking that my problems are stemming from a bad PCV as I removed the hose this morning, and plugged the manifold hole and everything went back to normal as far as idle.

I'll keep you guys posted
