Dont hate me if im on the wrong forum.................. i have a 2.2L cobalt 2006, i added a self made intake.....................3" stainless, i cut notch for the MAF sensor........al was good for the first 2 days........then i got a CEL showing "po172 system too rich"



by the way...maf sensor is now connecyed

non sai................................u see?

 

wrong section can the OP fix this for him.

PS: frist question should be " hi everyone I'm a new member. what up".

So hello new guy

 

thread moved to 2.2 section. welcome to the site.

 

its probably the design of the intake (no offense) and the location/position of the maf sensor. i cant see the pics here at work but i had issues with the maf when i put my intake on. had to go short ram for it to work, but i like it better like this anyway, throttle is much quicker and i made an airbox to keep the hot engine air out.

 

the bends in your intake will not work correctly for the car. You are making a huge turn right before the throttle body.

Also, your car will run like **** if you don't have a MAF hooked up correctly. So go look at pictures of aftermarket intakes and try to copy those designs.

 

Thats your problem. The intake pipe must also be a specific diameter, or the computer will think that there is too much or too little air.

Can someone let him know what the intake pipe dia. is supposed to be?

 

after seeing the pics now i can tell you what the problem is. #1 your maf is not in the same spot as before and are you sure its even facing the right way? there's an arrow on it that should be pointing towards the throttle body..plus those bends are nothing like what they should be. for what you spent on that you could have just held out and got the jdm intake. i'd recommend taking that all back and putting your stock on and wait til they're back in stock, or look for someone selling a used injen...

 

He has the right size....the typical aftermarket CAI/SRI is 3" and is made of 6061-T6 Aluminum, that is probably 304 Stainless steel that he is using....

Okay, you are in the right direction with cutting a notch...but that is not enough....what you need to do is take it to a machine shop and have them fabricate you a MAF Plate, i have dimensions in my gallery or what it should be. Have them weld it on, don't have an amateur welder do it....preferably somebody with 2+ years welding stainless or a certified welder. Next, after you you have the MAF Plate welded is to have some of that curve cut out (right before the throttle body), you want the smoothest transition possible, Not too much or it will not work. Take small amounts off until it looks relatively straight.

**NOTE: Make sure that the MAF Plate is welded in almost the same spot as the stock MAF Plate. Also, unplug the MAF Sensor and check to see where it is in the pipe before it's tack welded and after it's final welded, you want about 1/8" - 1/4" from the opposite side of the intake tube.

there you go.

 

actually i think he's using that do-it-yourself intake kit from autozone.. i saw one the other day when i bought my oil and filter.. looks an awful lot like what he's got. if so... its plastic :\

 

Nope. It's stainless, he even mentioned it in his original post lol

 

i know what he mentioned, but if you look at his setup, then check out the one at autozone or checker/parts america, its identical.. the long tube might be aluminum, can only find aluminum on the checker site.. but that bend piece is definitely plastic, its made by spectre performance. i saw a kit at checker identical to what his looks like and it was all plastic.. i'd say it was stainless too if it were me. once you factor in the time and headache of trying to put one together yourself, you would have been better off buying an injen.
