3rd Gen TL map sensor ruined cats
I have a 2004 Acura tl 6mt
My fuel system when lean due to a rigged up leaking air intake then I got a code for bad O2 sensors then catalyst efficiency low.. After a while running it like that I got a code for the map sensor being bad! My question is did a bad map sensor cause this chain reaction of sensors to fail? Also could the cat really be clogged or are O2 sensors telling me that?

reset the codes and go from there! IF they come back either the 2nd, 02 sensor is bad or the cats are bad. How many miles? Running lean can melt the cats and cause them to clog!
