i have 2 DTC codes, p0650 and p1133. It says there is a problem im bank 1?? i am totally clueless, can someone lead me in the right direction to solving this problem? My guess is something to do the the o2 sensor on the passanger side? can someone verify for me

thanks

Do you have headers? It could be something wrong w/ the o2 or if you have headers you may need the vette o2 sensors.. Search those codes and a lot will come up.

 

i have had headers for 3 years now though, could it be possible that 1 sensor went bad?

 

Probably so. Switch them and see if it throws the other code.
