ok i have had an injen cai on my car for about 4000miles now and i havent had a problem but the other night my CEL came on so i went to my dealer asked them to check it out for me. they were 2 busy to see me so i made an appointmen for today at 1oclock. well with my luck the CEL light turned off on the way to the dealer, had them check it anyway and they said it was throwing a lean code. now i kno a CAI can throw codes i dont kno what tho.
anyway he said they cant do anything for me bc the intake is on the car.
will a CAI throw lean codes and do you think its something i should worry about. the CEL light was on for like 150miles or so befor going off

Shouldnt have to worry about it, only if the light is flashing. I've had mine on my car for about 7,000 miles and no problem. The light just being on constanlty means an emissions problem. Next time, drop by an AutoZone, they can at least tell you what code # it is (i.e. P0304 etc.)

Its not the intake its the MAF i would say it regulates the air and those intakes are engineered to not throw codes. Is yours any earlier model mine has the MR technology and (knock on wood) no probs.

Im not to say that the installation was wrong, but was the MAF sensor installed backinto original position? The sensor has a "dog-eared" piece on the bottom side that must be facing towards the filter. Also, make sure there are no leaks right there at the throttle body, sometimes if the gasket or sleve works loose it can cause a code.

im pretty sure i installed it right simply because it worked fine for 4000miles and only threw a code for like 150miles and then turned itself off. ill keep an eye on it but as long as theres no serious danger to my car i wont lose sleep over it

Hold on just a sec...

yes it is the intake..effecting the MAF sensor not the MAF havening an issue...its doing what its suposed to do with a stock tune....the MAF tells the ECM how much air is passing through the intake air path thus giving the car the information need for proper air/fuel mix's at any given RPM and TPS setting.

an intake having "MR" or being designed to not throw a code are rather trivial in any sense.....any difference +/- 2% of expected air flow will throw eather a p0171 code(lean code) or P0172(rich code) depending on weather your over or under what is expected...

in other words any intake can throw a code...some are just better at geting the maf at closer to OEM placement in the air stream so it cant pick up all the extra air thats moving around it.....rather simple...however very hard to do.

if you were able to fit the maf in at the wrong direction i give you credit for braking the housing and/or sensor to make it fit....

this is just an example of what cars will do with an aftermarket part around a very sensitive piece..

my advice is to disconnect the battery for 15+MIN...then reconnect and drive VERY east but in all RPM's for 20-30min in hopes that ECM will rewrite some of its VE tables with higher cylinder air mass levels and maf correlations....normally they do.

There is a very simple fix for this.

Just take the car to a dealership and get the newest reflash. The CEL will stay away.
that re-flash is not 100%

I've seen 2 cars that had it done and it still came on....

one with the new style Injen and the other with an original K&N

some will, some wont...i suggest trying a differant dealer.

make sure to let them know that the re-flash is a GM issued flash...instead of recalling the car for such a trivial thing they send out these things so you can get the car flashed and avoid issue's for GM or the dealers....

and yes lol back to the rescue!

Exactly, there is a TSB out on this issue.

Take the car to a different dealer and ask them.
Some dealers want $90.00 for it some will do it for free. SOme just won't do it.

I know the reflash isn't 100% it's more like 95%.
It has worked for countless people. Hopefully you will at least try.

TSB's are warranty covered....

its to insure proper drive ability....they cant/should not charge you because its not your fault GM dident have this ECM revision when you got the car.

That's what I told my dealership. I told them i'm not paying for anything.

There is an issue with the original flash so fix it. They did.

It's all about who you talk to. Keep trying different dealerships until one does this for free for you.

I have an 06 Cobalt SS, with no supercharger. I also have the AEM intake, and I'm throwing a lean code. How much does the reflash cost at the dealership? This should get rid of the CEL right?

Nevermind. I called them and it's $115 if you don't have a warrantee, if you do have bumper to bumper, depending on mileage and year of coarse, I guess it is free for the reflash. This should take care of my problem then.
