Speed Density and Speed Sensor

I have a 91 GTA with "driveability" issues. Secondly, my speedometer works off and on. Could the two be related? Does the speed sensor on the tranny affect the engine at all?

Thanks for the help!

No not at all. It just feels like it has no power.

Shouldn't be anything related to the VSS then.
