Hope this isn't too far off-topic:
My girlfriends '95 Jeep Cherokee--4.0L six--has excessive NOX emissions.
A new cat got them down low enough to pass smog, but I figured it was
due to a stuck EGR valve. Well, I looked, and the engine doesn't appear to
have an EGR valve (it is FI).
Anyway, anyone know if this engine has an EGR and, if so, why can't I see it?
If not, what would cause an otherwise good-running engine to emit so much
NOX (400ppm+)?
TIA,
bs
