Hey guys i installed my cold air intake today. When i turned it on, it started making weird noises and right away my RPM drops and the car dies..??? anyone knows what the problem might be? thanks in advance

sensor is on backwards maybe. check that. and if that is good. try disconnecting your battery and reseting it.

Sounds like a vacuum leak. Make sure you got all your lines in place.

Thanks for the input. I checked the MAF sensor is the the right direction. and all the lines and hoses are connceted and still the same thing. RPMs drop and the car dies. any other suggestions??

Damn wierd.. Usually that will happen over the sensor being messed up, put in wrong, or theres a leak somewhere.. Check the coupler that connects to the sc and to the intake also.. I can't think of it being something other than that

it only goes on 1 way

what intake is it? did you drop/scrape the maf? because it does sound like you damaged it.

Iunnooo. Friends maf was on in the wrong direction when we put his intake on his wrx. ran like poop. like this guys saying. wasnt sure if it could be backwards or not.

UPDATE

Car is running normal now but i got the code p0172 system too rich. I took it for a test drive and the car has lost 40% of its power. in second gear it wont go past 4500k rpm. idles fine but huge power loss. any ideas what might be wrong?

P0172, my old friend "System too Rich"

Like the others said, check your hoses and everything. I see your stage II, with a tune, so you should not be getting this. Did they flash you back to stock? If they did, it would cause it.
I dont really see an intake causeing P0172, it would more likely cause P0171, but I guess it's possible.
P0172 means that your car is trimming out fuel past 20%. If all your connections are good, you might could check your O2 sensor(s)? MaF could be messed up, or perhaps you just need to have your retuend... These things sometimes can be so sensitive about a tune, they will throw an engine light if you change your shifter knob, and need a tune. (I'm exagerateing)
But ya, Check your linse, connections, for leaks and what not.
You can try some Injector cleaner,
and then you may just end up needing a new Tune.

Thanks for the info but why am I losing so much power? My car is literally redlining at 4k rpm

I say,engine power reduced............ because loose vaccum check maf to clarify the.maf.is good. P0172 can also be caused.by a lack of compression, bad plugs, bad gas, bad tune, unseen fual like meth but it sounds to me like vaccum leak or pigtail not fully connected.

How can i check if theres a vacuum leak? i just put in some fuel injector cleaner, and still no change. and also how can i test if my MAF sensor is damaged?

I doubt its maf cuz u will usually get a,maf error code. I say its a vacuum. Leak bad plugs or fuel... most it sounds to me is a vacuum. Leak..,get some brake cleaner spray on your vacuum lines and the intake. And the cai,like around maf sensor and the elbow for the cai. Have some one tune it also. A good known tuner.

Go to a parts store and get MAF cleaner. Don't use carb/choke cleaner on the MAF or you can ruin it.

p0172 had it for a long time. No leaks or anything, MAF changed never has come back since.
