hey me and my dad put on the cai today and we doublbled checked the maf to make shure we put it in rite. the arrow is suppose to face down rite? cause we tried other way but the screw holes wont line up so i hope i put in right, we drove around for 10 minutes but cell stayed on. Also when you rev the car in nuetrul it revs fine but after it comes back down it goes up on its own slowy then back down to 1k the normal. Any help would be great. Also i used the screws from K&n so i know thats not the problem.

 

I'm not 100 % sure but the arrow must be in the flow direction ... check on your airbox the side it was installed ...

 

The part about the rpms jumping up then coming back down is 100% normal. I don't know if it has to do with the electronic throttle or not, but mine does it as well.

Arrow should face in direction of airflow as said. Good luck!

 

did you make sure that you put in the screws that K&N gave you? that can be a problem, the sensor is really sensitive. if that doesn't work. disconnect the battery for like 10 min then reconnect it then drive it around for a while then turn the car off then back on. i'm just saying what i did to get the CEL off.

 

ok, just came back from driving it, started it up and no cell. drove for like 15-20 minutes then it came back on as i took off from a red light.

 

Did you disconnect the battery when you put in the intake? I heard that sometimes its normal for you to pull a code from this and it usualyl goes away after a few days or so.

 

you should have the code read, because it may be the pcm memory code, which is what you get from disconnecting the battery, which is nothing

 

my dad is going to bring his scanner home from work on monday so hopefully it is just mem code.

 

well tell us what it was as soon as you find out man. i am wanting to buy the k&n cai, but i heard that a lot of people are having the same proplems.

 

That is normal cause its a drive by wire set up...its like that on all SS's even with no mods.

 

I was reading in some other posts that disconnecting the neg terminal on the battery isn't necessary for new cars that on old cars you had to do that? Which is right?

 

Disconnecting the battery just quickens the process. If you didnt disconnect it, the pcm will eventually learn but it takes longer to take into effect. When you disconnect everything goes to the stock fuel and ignition maps. Then it adjust those maps as it needs to run within set limits. I hope this makes sence?
