Default Pulled some codes??

Pulled some codes today:

DTC #22: Throttle Position Sensor Circuit Voltage Low
DTC #41: Ignition Control Circuit Open.
DTC #43: Knock Sensor Circuit.

Is there anything serious in the above codes that should not be ignored? Vette is a 94 and has the Check Engine light on.

Note: A4 tranny strangely doesn't shift from first to second gear only above 3500 RPM! First notest this 4 months ago, but it goes back to normal after i let it sit for an hour or so! Dont know if it has anything to do with the TransGo that is on the tranny?

Thanx
