hi everybody, just bought a 2010 fit sport, runs great, i just installed a short ram intake, was running good, shut it off cleaned and waxed the car and it has a check engine light on, i checked the code p2647, what did i do wrong. Need help thank you

Hi, thanks for responding back to me, i went back outside and looked around under the hood, i forgot to plug in a plug i think it connects to the oil pressure switch. 1 more question, i installed a short intake, does the diode in the maf sensor face the filter, or the throttle body, motor seems to be shaking some, thanks
