what could the problem b a bad sensor or somethig else?
that sensor is expensive you have to finance it the dealer her wants $200.00+ for it

 

Buddy of mine that works at Ford told me that the PO108 is a barametric code in the PCM but it could also range from the map sensor even head pressures. He told me your best bet would be to take it in to an advisor and let them diagnose it.
