i just added air intake to my focus and now my check engine light is on. I think it's because i had to unplug the wires that connected to the bottom of stock air filter container and now that it's out there is no where to plug them into now.. also gas pedal is sticking. i don't think this is a really big deal but its never done this bfore... and third when i do a rolling launch it takes a long time to shitft into second. If anyone has ANY information please respond. thanks!
