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

Air intake, not gonna affect the afr enought to cause that
O2, good possibility. can go bad w/o throwing a code.... i had one go bad and lean my 7a out into the 18+ to 1 area without a code... injectors are another good possibility... but an O2 sensor is more likely.. and should be replaced every so many miles.. probably well overdue anyway.. -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.
