I've been hearing about these trap oxider diesel models and some sort of a recall to replace or remove them (not sure which) - are there specific years of these models ?
One year I heard is 1987.
Anyway, just want to be better aware of this while I'm on the lookout for a newer used diesel to be unloaded by a caring owner.
(Also, are there some diesels that use catalytic converters that I should be aware of ?)
