That nagging "catalyst low efficiency bank x" MIL that I finally programmed out last year?
Well I get a letter from Chevrolet today telling me that there may be problems with the "right or left catalytic converter", and they will replace it for up to 10 years or 120,000 miles. I wonder if they will do both?
It's not a recall per se, but a reimbursement. Just a FYI for you - and now I guess I'll have to unprogram that fault code back to stock...
