i got an 06 cobalt ss sc and im throwing codes p1101 and p0101.now i know that p0101 is maf and p1101 is air intake code. since i got the car the cars been going lean but running fine now since these 2 codes came when i start the car it idles real high then almost dies out and sometimes it does once the car is warmed up it idles fine and runs to a point where i can drive but once its turned off and i start it again it does it all over again,now when the cars driving feels like theres no power and in between shifting it feels like its bogging out..im not sure what the problem is but i did order a new maf and it will be here friday.Now my car has a cold air intake vibrant header and downpipe and megan racing cat back. please if anyone can help me out that would be great thanks.

 

If u have a intake tune for it or take it off. If u don't have a intake check for a vaccum leak. If no vaccum leak or boost leak then go to the route of either failing maf sensor, or exaust leak for lean code

 

it came with the intake and exhaust and ran fine but threw a lean code every once in awhile then it would just go off then flex pipe broke about a month ago then i put the header and downpipe on and it was running good til just 2 days ago when i tried to start it and it wouldnt stay running for a few mins then eventally after 10 mins it was running.

 

you need to tune for mods. Maybe the cars not tuned unsure... but make sure its getting fuel and spark, lean code could be because you have a exaust leak.

 

im pretty sure i dont have an exhaust leak.but imma double check everything again tomorrow when maf comes and im pretty sure i need a tune dealership can do that right any ideas on how much or about how much? the idle bounces around til it gets to 135F and then its drivable but up intil then it wont let me do nothing.

 

dOubt your maf is the issue. Clean ure throttle body plate for the bouncy idle. Dealership can not tune u because all theycan do is mfg
tunes so they can't help

 

so problem solved changed all the vac hoses nothing same took intake apart and found a hole fixed it tried it and the same thing so i changed the maf. and problem solved.still got a little bounce for the first intial start but that goes away and runs alright now. but i found a place around my area that can tune it for me thanks for the help.!!!!!

 

so after driving around 50 miles cel came back on now throwing codes p0171 and p1182...

 

system running to lean and i think p1182 is a evap cel im unsure id have to look first. lol

 

yeah if you can do that that would be awesome thanks.

 

hey let me know how this turns out. I have a similar issue except 1101 and a 0172 system too rich. Not sure what to do. i have 62k miles on an 07 ss/sc.
mods aem intake and exhaust

so far i have tried maf cleaner but the code came back.

 

if your car was running like how i expained it and if your throwing the maf performance code i would change maf and for the new codes that came up to lean in bank 1 im not to sure yet but im looking into a place by me to get it tuned so maybe that will take them codes away.

 

Hey same problem p1101 except its running rich, if I need a maf do you know where I can get one orhow much they cost?is it a dealer only part.

 

Ure intakes or exausts will cause this. Po172 usually means your car is commanding say 14.7 but u are actually like 14.0 and so forth which would be caused from performance parts that have not been tuned

 

Interesting, any reason this would happen 3.5 years into having the AEM intake installed?

 

cheapest place i got my maf is advance auto like hundred after i returned the core.so pretty much i need a tune correct? if thats the case imma just go stage 2 and get and dual heat exchanger and get it tuned with everything on.

 

Sure bro. U could possible have a leak after the
maf meaning a vaccum leak.... Bad maf, exaust leak

 

Damn, I am putting in my stock intake tomorrow , got one on ebay. Do you guys think the dealer can find the problem?

 

well back to stock for now then off to the dealership monday.

 

got my new intake today going on tomorrow well see if that changes anything.let me know how the dealership goes.

 

haha heres the kicker, light went on today on my way to lunch around noon, drove home went to store and the cel was gone! Seems to turn on at idle. I was suprised even though its the stock intake.

I think my plan is if this light stays on i can go to the dealer. But i cant go there with no CEL or they say they cant fix it.

What a pain in the ass!

 

haha well if it stays off intakes the problem and then pretty much all you would need is a tune with what you got.run it the weekend with stock intake and see what happens
