1993 Crown Vic ( Check Engine Light on)

What are some possible solutions to get the light to go off?

Also my Speedometer has stopped @ 142,403 and the one below has
stopped to? Any fixes?

Please help!

It is likely that yur vehicle speed sensor has failed
preventing the ECM from knowing how fast your are traveling.
This not only screws the speedometer but, the transmission,
the engine emission controls, the antilock brakes and
everything else that needs a speed reference. Have the
fault codes read from the ECM and go from there. Once this
is properly repaired, you will notice a major improvement in
other vehicle performance areas. Until this is done, the
light will remain on and your vehicle is limping along using
more fuel, emitting more polution and a general PITA to
drive.
