Altima missfires

I have a 95 Nissan Altima with 170,000 miles that recently started to buck and cut out on acceleration when completely warmed up. It had the following codes. Camshaft sensor malfunction, Vehicle speed sensor malfunction, EGR flow malfunction, and knock sensor malfunction. What should I do?

Needs Waxed.............. and Armorall Doncha Know now!@!!!!!!!!!!!!

Check your Seal!!!!!!

Block the EGR Part, and see how the car runs.
