o2 sensor? #2

[m82z]

would a bad or diconnected sensor cause the exhaust man. to get red hot?
or is it something else?

[Jim Keller]

No, sounds like your cat is plugged. However, if your looking at it in total darkness right after shutting it off, it will have a red glow to it, but should not bne bright or noticable with much lighting

could i just eliminate the cat , how would i check it? exhaust seemed to be o.k.

If you want the system "stock" replace the sensor. They run
from $30 - $50 depending upon the vendor. Easiest way is
to drop the dual exhaust pipe from the cat forward, then take
off the "intermediate section" beneath the exhaust manifold
where the sensor resides. Persuation to free the sensor threads
usually requires a propane, MAPP or acetylene torch to get
things nice & toasty. Old sensor out, new one in, exhaust back
together, quite straightforward. Lots of fun . . .

sounds like a real kick in the head! thanks

Beta/Betas ain't easy to work on. Scorpions [engines] are a
breeze to work on by comparison. If you end up attacking
your exhaust go back w/ALL STAINLESS [or brass] nuts, bolts
& washers doped w/MoS2 anti-seize. Sensor threads too!

[Jim Keller]

Run the car and watch for the exhaust to become extreemly bright red between the engine and cat. If it get red glowing hot, your cats plugged. Yes, you can run without a cat if you do not E-Check in your area. But cats are not real expensive. I never remove mine anymore for my street cars, it makes no real performance or fuel mileage difference

jim, thanks. any suggestment on reasonably $ replacement?

[Jim Keller]

There's a lot of used ones laying around people's garages, you could post a "Parts Wantyed" ad here and probably come up with a few, but if you don't want that route, and universal is ok, just about any auto parts store or muffler shop will have them. If you go aftermarket, you will have to modify the connections most likely, a "good" muffler shop can do it and it shouldn't cost too much for the labor. Universal cats run around $130. Make sure you stick to the same diameter pipe
