I just installed a cold air intake on my 05 F150 Super Crew. almost immediately the check engine light came on. I've taken it to have a diagnostic done. And the only answer I keep getting is that my truck's computer doesn't like the new intake. And the increase in MPGs that I was supposed to see not only didn't happen, but I'm burning more gas now. Does anyone have any input or advise on how to fix this problem?
