Or does Sanderson Ford (Since they are a performance dealer) tune your car and let you keep the warranty intact? Does any one have any ideas?

i had the same problem with my '00. i have a K&N and no more than a month of having installed my engine light came on. it turs out that it was the mass air flow sensor that set it off.
