Possible wheel alignment or balance. Have front end checked

sounds a little like a cruise control problem.
they used to have a centering adjustment that kept the speed within a range. If the range somehow shifted to the high end this would cause your surge. it would be a screwdriver slot on the outside of the case.cw increase ccw decrease. yours is set too high or cw.
I work the screw back and forth several times in case dirt entered the cruise module.

cable sounds to be broken by description given

check and see if the wire on back off speedomter is loose and check your vehicle speed sensor see if working or broke and you also have wheel speed sensors that could be malfunctioning

I would take a blind guess and sat the speedo sensor has an issue. 99' beetle should have an 01M auto, and the speed sensor is also the dipstick for the final differental drive. search around this area of the trans for the cable and snoop around. loose at the trans ? bad connection somewhere??

most certainly a speed sensor problem!
it may not be pulsing properly or the drive gear is worn etc etc.

change fuel filter have injection system cleaned

I believe that would be the VSS or vehicle speed sensor.. Its located on the rear axle.. I would get the part directly from a ford dealer as the one I got from an auto parts store did not work correctly.. It cost about 33 dollars from ford and It is an easy change for a do it yourself person.. Kip
