check your owners manual....you can run a diagnosis through you trip odometer...it will give you a code so you can pinpoint the problem...

Is that in the owners manual thats in the glove box,or is that the ford factory manual ? I'm sure there's no manual in the glove box ,Her friends reset(?) the the computer last wkend .I'm sure she said the engine lite came back on.Everything seems ok,ie: starts good drives ok etc. The proceedure would be nice .
