it appears that you have malfunctioning gages. this is most probably a malfunctioning sensor at the transmission speed detection unit (SDU) take your automobile to your local shop and get a qualified technician to diagnose your malfunctioning SDU

That would make the lights on the gages and warning lights cut in and out along with eat and gas needle?

This is a known problem with these cars. My '08 Grand Marquis is doing the exact same thing. There's a wiring harness that gets pinched between the top of the steering column and the bottom of the instrument cluster. Over time the wires get chafed and an intermittent bad connection to the instrument cluster is created. The steering column must be removed to access the wiring harness for repair. Best to let your local Ford Dealer fix it. HTH. -Jim
