I got an 01 Monte Carlo LS. I’m having trouble getting the evap and egr monitors to show “ready”. I was wondering if any of the following things could prevent the computer from completing the drive cycle.

-there is a recall on my cars ignition switch (where the key goes). This recall has not been completed.

-aftermarket stereo installed with the basic wire harness. Not with the integration interface.

-traction control and abs automatically turn off due to a bad speed sensor.

If none of these affect the drive cycle, what are some likely causes. Any info is appreciated. Thank you

oh and there are NO current, pending, or saved trouble codes. No check engine light.
