I know what it is, but I'm just wondering what people think of why I got it today. I've had my CAI for months now, but this weekend I changed out the hose from the intake to the valve cover for filters. Do you think it could be the filters? Thats that only thing I can think of. I cleared the code with a tech 2 and drove it up to school and it came back. Car's going in on friday for reflashes anyways, so I'll have them clear it again then, but i'd rather not have a repeating code all the time so I want to figure this out. Anyone?

bump

make sure everything is tight and sealed up. other than that just delete it.

i did clear it and it came right back. i really think its the breather filters. im going to switch it back to the hose tonight. do codes just go awayif the issue is resolved or do they def need to be deleted?

So you put filters in the PCV line? (If I'm hearing you correctly). You aren't gaining any performance, and I would just put the line back on and the code should go away. Also, there needs to be vacuum on the PCV for it to work correctly.

put the hose back on it.

yes! put it back on asap your car is and will run lean without that i did the same thing ive done it on many other cars and never had a problem but that is for sure why the light is on hook it back up :nono:

yeah it was stupid on my part. i put the hose back on and hopefully tomorrow itll run better. does anyone know if the light will just go out or whether ill have to delete the code again? not a big deal, just wondering for the sake of knowing

the light will go out but it will take a long time something like 100 key cycles or something just clear the light if you can or go to auto zone and barrow / use there scanner its free but you have to leave a deposit hope this helps

just disconect you neg battery cable for about 10 min. reconnect it and the code will be gone.

thanks. i have access to a tech 2 so ill jsut clear it

You have access to tech 2, like the actual GM tech 2 program?

like the unit and the programming software that goes along with it i guess
