hi brickboard,

i just replaced my cat in order to pass the emissions test. my "old" cat was replaced two years ago which seems early for cat failure. this leads me to believe that either it was a bat cat converter or my car killed it.

is there anything i can do, in an otherwise fine running 1990 240, to make sure the car is not poisoning the cat?

the O2 sensor is only a year old,
new plugs
1 1/2 year old FPR regulator, cap, and rotor
new air filter
2 year old wires
new fuel filter

250 000 km

thanks in advance,

cat
