me an my bro made an intake for my car it works good but my check engine light is always on sometimes is turns off to idk anyone with intakes ever have this problem

 

Boy oh boy.

My CEL came on and off for about a week. Now it went away for about a week and half. I heard that those lights for the intake could be just as simple as disconnected the battery to let it reset and read the new system. Some say they just ignore it. But just get the code of the CEL from your local Auto store, and come back here on one of the stickies, and find out whats the problem.

EDIT: I re-read your post...It said you made your own intake? That could be the problem.

 

Welcome to the world of aftermarket cars
did he happen to make a way for the MAF sensor to hook up to the intake pipe?
Try unplugging your battery for an hour
Because you made this for yourself, chances are the CEL is never going to go away

 

If you have a turbo motor take the intake off. If you have another motor, then you need a retune for it, still probably need to just throw the homemade intake away.

 

listen to him ^^^

 

Thats your problem...

Search as there are many threads about installing intakes and getting the check engine light.

 

Hopefully youe maf sensor is positioned correctly.(must be straight to the travel of the air coming in)
A little crooked and it could cause a cell.
Dont let these guys bash you until you post a pic of it.
But great that you gave it a try ,I would to if I had the proper equipment.

 

yeah ill post some pics of it tomorrow

 

i don't think i've ever heard of anyone getting any codes because of their intake... weird

 

Makes you wonder whats wrong with his.

 

You have two potential problems:

1. You have increased airflow beyond the range of the MAF. A tune could probably correct for this.

2. The MAF is not in the correct position and you are getting incorrect airflow readings.

The only way to know for sure what the exact problem is, is to get the code read and do some logging. If I had to guess, I would say that the MAF is probably mounted incorrectly and is not getting the correct airflow measurements. The only way to fix this is to re-engineer the intake.

 

Yeah, instead of going through all of that, I would just buy an intake. Unless if you have no money or just plain bored.

 

I'm sure that you have to be joking. Ihave read atlest 3 in the past two months that have appeared in the 2.2 section...

 

i was absolutely joking. this is probably the most talked about thread in the history of cobaltss.net... after the girlfriend threads.

 

Actually 2 seperate problems could be the deal. VAC leak. Or maf problem due to positioning and/or increased flow. If it's flow related you need to tune for additional air flow. Position cel problems are more/less related to flow anyway.

 

Put the stock one back on and the CEL should go away and not come back. That will show you that the problem is your homemade intake...
