Throwin codes and dont know why! Keep in mind i have the AEM intake and SS exhaust, well half the SS exhaust the back section is not on the car.


P0171 System too Lean (Bank 1) This is a new one tonight!

P0103 Mass or Volume Air Flow Circuit High Input

 

Restriction Releases = Lights.

 

it makes sense to me. Your messing with the air imput & those are the Codes that you are throwing. That System too-lean one is kinda Scarry Though. if you were running a little Ritch to help out w/ knock retard thats one thing. I think these cars run rich from the Factory though. Good luck chasing it.

 

Sorry to hear that Kyle. I think it might have to do with the intake, but it's a dryflow I thought. Could always try taking out your MAF and seeing if it is dirty in anyway.

 

good idea... also make sure all connections are tight... usually a big problem with the intakes

Thats what alsmot everyone was getting with a CAI. Did u disconnect battery when u installed it ?

P0103 Mass or Volume Air Flow Circuit High Input

MAF failure is at 10,000Hz . Did u got up to 6500 or 7 grand ? with the CAI

Never got the lean code but i did get the P103 with my CAI just on the base Stage 2 but the i had to bump up the MAF fail.

 

Get a GM stage 1 or 2 and you wont have those codes again. When I had a K & N

typhoon code p0171 came on every week. After I installed stage 2 it never came back on

and had no problems what so ever.

 

just go to the dealer and tell them you have a check engine light there is a new tsb for the cel on cobalts now and mine has been off for a good two weeks (crosses fingers) and i have a injen cai and its been all good for me.

 

i hate trouble codes

 

He has a 2.2

 

I was wondering how long it would take people to realise that.

First time I've heard of a lean code on the 2.2....

 

i had a cel on my 2.2 when i added the aem cai and when i took it to the dealership they made it go away and has never come back. that was over 8000 mi ago. i think it was from touching the maf while changing the intake pipe. the tech said they are super sensitive to foreign debris. not sure how they cleaned it though.

 

well i cleared it and it hasnt been on lately?? Its dumb and runs like ass when codes thrown! MPG goes way down and kinda cakles and pops at speed? It runs really rough. The exhaust will be finished asap hopefully that helps adn comp reset again tomoro.
