Hi gang, has anybody here heard of and or has experience with a product called CRC-Guaranteed-to-Pass-Emissions Test?
Reason I ask is I have inherited a 1985 GMC Sierra Classic 1500 that had failed smog test, It is completely stock and original, has a 305 backed by an automatic(I'm guessing it is a TH350). It is a California truck with a cat converter. The cat and Flowmaster muffler are supposed to be fairly new.
Thank you in advance for any responses,
