On a Chevy Cavalier? 2001 Z-24, what do you think? Can negligence to perform maintenance on any of these lead to major problems for the engine, or transmission ?

Answer 1

NO THESE ARE JUST EVAP CODES, VAPOR COMING OFF FUEL IN THE TANK.  

Answer 2

try putting a new gas cap on and get the light turned off. alot of these codes are regularly seen when a gas cap is left loose or off. if that does not help look for a bad line on the evap system.

Answer 3

First poster is correct but you shouldn't have all these codes at the same time either.  Something else is wrong.  A computer going bad is a bit of a concern to me.  I would get the light turned off then as soon as it comes back on get it checked right away and that will clue you in a little bit better as to what exactly is going wrong.
