Oh I love CEL's while driving up-state

[ryanworth]

Hey all! Well while driving upstate to AZ10 I started getting a few CEL's. [o_o]

Symptoms were the following:
rough idle
surging RPM's (meaning rpm's would drop to 700rpm and almost stall and then jump to near 2000rpm and stay)

P0507 - Idle Air Control System. RPM Higher than Expected
P0171 - System Too Lean (B1)
P2293 - Fuel Pres. Regulator 2 Perf.


So I am aware that its my PCV and Valve Gasket. No I'm not really losing boost, it's holding strong.
I'm also aware P2293 is related to the fuel-cuts I receive. I will be checking my cam follower to be safe.

My question is do I need to replace the breather tube and what about the MAF being effected at all?
Any other input or parts I should check?

Thanks! And here's a picture because people don't look at threads w/out pictures.

I replaced the Breather Tube because it came with the kit. But it really wasn't necessary, it looked fine.

I'd only replace your breather hose if your car is screaming like some chick on her menstrual cycle. srsly.

And if your MAF was affected you'd be getting misfire codes.

Good to know about the breather hose. Saves me $50.
And I figured I was good with the MAF, but never hurts to check.

Thanks fellahs

The first 2 codes are related to your PCV, just need to replace the valve. I had those exact same codes and I replaced just the valve and that solved the problem.
