so my '94 celica gt failed its emission test again (2nd time) this past week. it gave me the same reading that im making too much CO. i changed the oil, oil filter, air filter, sparkplugs, even poured in a bottle of seafoam into a full gas tank..and it still fail. i was given a few options b4 my next emission..either i replace the knock senser, or replace the O2 senser (a buddy recommended either, or both). just curious if u guys can piont out anything else that might b causing this high level of polution..just anything. thanks.

is it just your CO that is high? or are other things high too?
when was the last time your air filter was changed? also, you could try the O2 sensor as well.
