1995 Oldsmobile Achieva 6 cyl Front Wheel Drive Automatic 70000 miles

Hello,
Below 60mph the engine light does not come on. Above, it comes on and trips a code 77.
I replaced the EGR, replaced the tube, reset by disconnecting the battery, then through dealer.

It still triggers the code and can not figure it out.
