CA Smog help
I am running the original Cat but it shows no signs of clogging that I can
tell. The O2 sensor was replaced four years ago.
88XJ 4.0 non HO 180K miles or so.
New wires, cap, distributor. Fresh oil change. New Air Filter. I had
a friends shop put the smog sniffer on it. He says my CO is at 135.
It should be less than 100 according to him. After doing some research the
numbers don't match up to what I am reading. There are no CO numbers
anything like that anywhere. I also need to go to a
test only. This is the first year they ever made me do that. Does
anyone know of a few things to try before I send it to someone to
take all my money? I only have until the 8th of December. Anyone
know of a reliable shop who can fix it if I cant? I haven't changed
the plugs in a while (30k miles maybe? don't), I will do that for
good measure.

Would 89 octane help or hurt the process.
Someone also mentioned an additive product once.

Re: CA Smog help
Hi Kevin,
Here's what our tests look like: http://www.----------.com/smog.jpg
I've always asked up front for a pre run and they charge me double for
that, but at least I know I won't be branded a gross polluter and put on
the yearly test. Make sure it's running at full operating temperature,
195° thermostat, have your oil up around there too, that usually takes
about twenty minutes of freeway driving, then don't turn it off during
the time you're waiting for your turn to be tested, so the catalytic
convert stays at 1600°. Good luck.

Re: CA Smog help
It may be just smoke and mirrors, but I replaced the cat on my 88 MJ
(160K on the 4.0L) and the CO numbers took a real dive. There was no
visible sign of plugging. Also, 4 years on an O2 sensor - depending
on the milage - may be a little long with that many miles on the
engine. Even if you don't use much oil (I change oil at a quart down
or 4K miles, whichever comes first) you are still passing a lot of
crap with 150K+ on the engine.
I replaced the O2 sensor a couple of years back and it did wonders for
the idle (and the color of the tailpipe <g>) then replaced the cat on
speculation this year as I felt that the top end and highway
performance had deteriorated. I did get a noticable improvement so
the cat was probably plugged a bit.
New plugs, a fresh oil change, and a clean air filter will help keep
the sniffer happy on both ends of the test. A friend who runs a
garage and inspection station swears that cat performance degrades
over time. He suggests that you take the car out for a 25-30 mile
highway run on the way to the test, btw.
