ok bro, sorry it took so long, the site was down for a bit. Remove your MAFS with the two screws. Clean it with a q-tip and throttle body cleaner. There is a detailed explanation in the how to forums here. I don't know the blitz filter, but it seems odd that there are no vacuum lines? I know that will throw a cel on a Injen
or AEM CAI
if there is a vacuum line hooked up wrong. I personally don't think its your MAFS as you should notice a performance/idling problem. But it never hurts to clean it! Try re-setting your ecu like suggested above. If not, I am sure tjat v3nom can help.
