it started when we changed all the brakes on my 2004 coupe. everything was fine except the brake light was on. the reason was that we had forgot to bleed the brakes. great, so we did and everything was fine until a week later, i get an abs light and decided to ignore it. 2 days later i get check engine light. now i have the "steering wheel" light, check engine and abs on all at the same time. today i went to autozone and got my car obd scanned and got the codes P0600 and P0720. after reading a little on the forums.. i am still confused. can anyone help me?
