So this past weekend i installed the injen intake.... i drove it around for a couple days and then one morning the CEL turns on when the car turns on... like what could cause this... i hope its not the intake cause thats not coming off..... also i dont know if it mab installed wrong or not but when i shift into third gear it makes a raspy noise off the filter... tell me what i should do cause i need to take it off my car... and im not buying a CEL eliminator so dont mention it...

 

Get the code checked at autozone or a local parts store... most do it for free and tell us what it is... it's nothing to do with the exhaust, which is where the CEL eliminator is used.

With the code, we can tell you much more...

 

what do you mean the code

 

The CEL comes on when there is a code to display an error on the cars ECU... you, or a parts store can plug into the OBD-II port to read the code and know what the problem is... there could be literally 100 things that the CEL could light up for, the code tells us what is really making it light up...

 

im thinkin that the MAF sensor might be sensing too much air or something... it has to b something with the CAI since it was just installed and the CEL came on like 2 days after

 

It shouldn't have any problem with air or such... I ran the same intake for more than a year without an issue... I'd check the code, and also check to make sure the MAF sensor wires are clipped on securely as well.

Without knowing the code, it's a shot in the dark...

 

You might have damaged the MAF

 

now just say i did damage the maf sensor... how much do these things cost new... i have a feeling they are like 300 dollars

 

yep... they are about that... not cheap at all...

 

A pretty penny I believe.

 

how would i know if i damaged it or not? is there anyway to tell?

 

diconnect the battery and reconnect and it should go away, for some odd reason it happend to me too and the whent away when i diconected the bat.

 

Disconnecting the battery resets the ECU and eliminates the code... I'd still get it checked for free prior anyways. if you reset it and it comes back... GET the code read.

 

I had the same problem with my Injen CAI, the only wierd thing is my CEL only started to come on after I got my car back from the body shop (I rear ended someone). The dealership service center said the codes said my engine was running to lean, and most likely because of the CAI. I started running premium (91 octane here in cali) and haven't had a check engine light since. I haven't had to reset my ECU in a long time either.

 

aight i will disconnect it tomrrow morn and see what happens... i will follow up tomorrow afternoon sometime to tell you what happens....

 

might sound weird, but have you gotten gas recently? My wife through a CEL and took it to the dealer and low and behold she hadnt tightened the gas cap properly and it through a CEL.

 

that happened to my sister a while ago when she barrowed my car. boy, was i heated, but good thing i found out what happened before i drove down to the dealer.

anyways, did you disconnect the battery when you installed the intake? if not, you should be set just by resetting the ECU.

 

Happened to me recently too. I have had an injen CAI installed for 3 or 4 months.
The car felt sluggish and I thought nothing of it. A half hour later I notice the CEL is on. I took the car home and ran my errands with my wifes truck, when I got back to the car and started it the RPM's were jumping from 3-500. Eventually it would stall. I tried EVERY method of resetting the ecu and nothing worked so I put the stock box back in and had it towed to the dealer. An hour later I had a new MAF sensor under warenty.

 

get the code checked out, it may answer some questions
