Evap Emission High Purge Flow Fault is what read out on the little computer deal at advance auto parts. The CEL came on 2 days after I installed the ZZP 3" CAI...I had the guy clear it but what I'm not sure what the exact problem is. Makes me not want to even put anymore freakin performance to the car if there is goin to be a problem everytime...only has 23k miles on it. If you need anymore information just ask I'll give you what I know. Thank you in advance.
