P0131
P0140
P0151
p0160
p0512 (this one i assume was because i hadnt started it in so long.
i thought id only get codes for the rear 02 sensors, do these codes indicate my front 02 sensors are bad?
Also i get a flashing ses light when driving over 60. 4L60E 2002 Camaro SS 38k miles.
thank you so much, jsut feeling anxious since i found these new codes
