p2195 and u0073
 

hi guys,

i just got p2195 and u0073 codes on my frs, i think the issue might be a bad main harness connector or a bad tune? does anyone have any experiance with those codes?

im using aem wide band and it looks fine just as it was few months maybe tiny bit richer.

so before i try to retune or change the 02 sensor i want to hear you opinion.
