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

you should invest in an A/F gauge. even if it is stock, it always helps to have a constant check on how your car is running.
