the other day me and my friend put a cold air intake on my 97 impreza 2.2 and it started runing like ************...dosent like to idol cold and trys to limit me anywhere it can up to 2500 rpms and keeps tryin to when im just driveing...so we thought put the stock intake back on...we did and it idols now just keeps trying to limit me...any ideas on how to fix it?

my gas mileage also went down alot...any ideas?

the MAF.....

did you hook it back up.

maybe you killed it somehow.

ugh i hate these so much...its hooked back up but the 4 orgnail screws are no hooked up theres only 3 i lost one in the mist of changeing the intake infront of autozone and home depot...i cant realy think of anything else

go back to stock, make sure that you haven't picked up anything in your air filter, you'll clog an airfilter quick with a CAI.

 

Make sure your IAC is connected still.

 

BTW, all Subaru's come with a CAI stock

oh thats great and it should be still but ill check again

i dont think we played with the iac

Did you buy an oiled filter?

 

Filters with oil on them are notorious for covering the MAF sensor with oil and "numbing it". It won't read the proper airflow when it's covered in oil. You can buy MAF sensor cleaner or electronics cleaner and spray it on the sensor to clean the oil off if that's the case.

 

The other thought I have it, what did you do with all the large hoses that attach to the stock airbox that mounts to the throttle body? Did you disconnect any of them?

yea i gotta pre oiled filter and when we put the cold air on we left the hoses layin around and when i put the stock intake back i hooked them back up and never thought about that

thanks fairtax4me that was the problem
