Help guyz I only have a AEM V2 Cold-Air Intake and a Apex'i VAFC II V-Tech/Air Fuel Mixture Tuner....I recently went on the highway and first through fifth there are no problems, then in sixth at V-Tech the check engine turns on (SOLID)...So I know it is not serious...I got it checked out by my tuner and he said it was "Secondary Air Injection Flow" this was the problem which made zero sense to me and the tech...I need help am I screwed with this car does anybody have the same mods with the same problems or no problems at all...BTW when the check engine sign does come on it is like a rev limiter at about 5800 RPM I NEED HELP SORRY FEEL LIKE AN IDIOT!

 

I guess you have to check your settings or the wiring.
