Car will miss around 50-60 mph. If I floor board the gas petal it run great but if I do not it will miss around 50 to 60 mph, after that it runs fine.

Hi there,

this may be a spark plug breaking down under load, do the tune up first and get a run on an oscilloscope as this will give all the ignition voltages and will be a good guide to locate a fault in an individual cylinder.
