My check engine light came on the other day, so i went to auto zone and got a free diagnostic test. The code was 402, which reads...
"Exhaust gas recirculation flow excessive detected." "The exhaust gas recirculation system."
The salesmen at auto zone doesn't have a clue what that would mean, and neither do i... Anyone know what needs to be replaced or done to correct the problem?
