Last summer the first catalytic converter melted and clogged the second one. I punched out the second and replaced the first one since that is the one with 2 oxygen sensors connected to it. Since I replaced the cat I've put about 20K miles on my car. The cat. melted and got clogged again.
Does anyone know any reason(s) why this is happening? -220K miles (2.2L) -Engine is running at normal temp, never over heats -Doesn't burn hardly any oil, maybe half a quart every 3,000 miles. -It is eating gas, though i think that was from the cat being clogged and it needing extra to keep the engine running under the increased back pressure from the clogged converter. Here is a pic of what it looked like before I punched it out today

yea you dont measure resistance of the o2... and its the precat o2(first one, in the exhaust manifold) that will affect afrs.. the post cat (further down the exhast stream) is to make sure your cat is working
