93yj failing
Ok my 93yj failed emissions miserably today. Hydrocarbons by just a little
but CO by well, a HUGE amount. Nox was barely noticable... I did the whole
tuneup about 4 weeks ago but also had a gap develop between the header and
pipe (before the o2 sensor). The tuneup got rid of my backfire problem but
the exhuast problem is making my Jeep sound horrible. I think it's also
causing my Jeep to run real rich (stinks) and it has a noticible lack of
power. Any screwed up logic here? Anyone have anymore suggestions on
solving this? I'm thinking about just having my exhaust rebuilt from the
header back, but I don't know if that will solve my emissions prob.

Re: 93yj failing
OHya forgot. It's stumbling badly on idle. Missfiring. Is there anyway to
tell which one is missfiring? It's the 4cyl.

Re: 93yj failing
Hi Nick,
Your mechanic will tell which is misfiring by a balance test using
their diagnostic computer, which short each plug individually, measuring
the change in revolutions per minute. You may do the same by pulling an
ignition wire, until you fine the one that doesn't change the RPM.
I'd fix the exhaust, letting oxygen in is bound to screw up your
Oxygen Sensor, probably enriching the mixer to compensate, further
screwing up your tests. And replace your catalytic convert which will
burn the Hydrocarbons and change Carbon Monoxide into harmless Carbon
Dioxide.
