so i have a 2.4 cobalt and i just installed the k&n typhoon. everythings on fine. so i started it up, and it almost sounds like the car is coughing. like it idles very low and sounds like its dying! whats going on??? ugh.

if it helps, i have a header and catless dp. i do have a cel. idk if that could be a reason...

 

what the cel and call k&n and ask them about helping you

 

i havent found out what the cels for, but im pretty positive its for being catless.

 

did you tune everything out??

 

so i didnt really think this could happen, but it did. my maf sensor is backwards!!! i didnt make anything of it when i installed the intake, but i called k&n, and they said it wasnt normal. they sent me a shitty intake tube. here are the photos, if you guys are confused onto what i mean. they are sending me a whole new intake kit (hopefully it works after i get this fixed)

 

haha told you to call them and thats good at least there taking care of it is yours at least carb legal?thats the only reason i havent gotten the lnf one yet

 

There is never going to be anything c.a.r.b.ed for cobaltss/tc other then AEM and only for 08 year, not 09 or 2010, i emailed them and asked if there were going to make a c.a.r.b. intake for the 09 and 2010, they said most likely not, because there was not enough cobaltss sold to make it worth the investment of making the parts c.a.r.b. approved, i got the same answers from K&N, zzp, and tredstone. sucks

Sensor would be my guess. take it out clean it!.. might just be bad and have to replace it make sure that when you were doing the swap you didnt bang it up or anything.....

 

never say never k&n and injen both said they put the carb aproval in for every intake they make but that doesnt mean it gets aproved

 

well see......hope so.

 

eh my buddy has a carb aproved k&n ss/tc intake its a k&n intake with a aem carb sticker on it lol i had a 94 cavalier with a 96 and up 2.2 injen intake that was carb aproved and i passed smog every year just fine

 

some smog guys are to lazy to look it up, it takes like 2sec, I fail peaple for it all the time.

 

haha yup my guy looked down and said **** it even got pulled over by a cop and didnt get a ticket dumb *****

 

did you not notice the arrow pointing in the wrong direction
also if the maf on your le5 is like the one on the lsj you can just turn it around cause its not keyed. which would mean k&n didnt **** up and youre getting a free intake out of it for not paying attention hahhaa

 

um you dont think i tried to turn it around? it only screwed into the intake while being up-side-down. and of course i noticed it, thats why i called k&n....???????

 

read bold

 

You screwed them. Good job.

 

yea.
