·The engine light came on yesterday. (I was returning from a 300 mile drive.) I took it up to Auto Zone and the guy read the codes as 420 and 430. He told me that it is probably the cat. converter. Said it may be clogged or need changing. This guy also told me to try a can of "Guarenteed To Pass" fuel additive, come back in a few days and let him reset the CEL and see if that might do the trick. I'm leary of this advise. What do you guys here think? Should I try the additive? Or, should I simply take it to the Toyota dealer and trust their directions? :roll: (With 52, 000 miles and no previous problems, I guess I can't complain much.)
