How do I check for errors that the car is making?

 

Are you talking about error codes??? If so the simplest way is to take a paper clip and ground on the diagnostics terminal for your ECM. Buy a haynes manual and it will tell you how to do it in there.

Oh yea, you spelled camaro wrong in your sig....

 

Put the paper clip between the top right 2 holes in the ALDL plug under your steering column and that will cause your check engine light to blink the codes with the ignition key on and engine off.

 

Easiest way is to put it on a scanner.
