CAT problem
Hi..I have a 99 Civic and I had a dealer put a new catalytic converter. In the last few days when I go uphill and I accelerate I hear this hissing sound coming from the catalytic converter. Is it possible that the catalytic converter is clogged or what could be causing this hissing noise? What should I do???
