what causes the emissions control system waring light to come on in a f 150 2005?
I also practice martial arts (taekwondo). So, I imagine that taking down, neutalizing someone w/ box cutters would be easier.
I would not even Pi$$ on a terrorist if he was on fire !! What's a box cutter ?
Leave it to the police, don't take a risk.
Many things. First thing to do is check with Ford dealer to see if there is any emission warranty left on the truck. Some things are covered for up to 8 years. I have seen many people try to save themselves money by fixing themselves or going to fly by night mechanics and putting on hundreds or thousands of dollars to try and fix the problem when it is a $5 cracked hose or gasket. After you fix it yourself or go to other tech, you can not go back to Ford and ask for a refund, so at least check there first.
Any number of things, clogged cat or exhaust, O2 sensor problems, vacuum leak, .and the list goes on. Your best bet is to take it to an auto parts store like AutoZone or Advance Auto, they'll scan your trouble codes for free. Sure beats going to a garage and spending an arm and leg for diagnostics alone. If you're capable, you can then fix it yourself, or take it to a garage and say, Hey replace this., and getting it checked ahead of time saved you some serious dough.
