Glowing cat
Hello,
I finally finished retiming my 91 Civic DX (1.5L 16V) and as I had the engine idling in my driveway, I noticed that the cat was glowing red. I'm assuming that this is a sign that the engine is running rich. I don't get any check engine lights or anything abnormal. The engine stumbles a bit taking off, but seems to run fine. What could be causing this?
Thanks,
Mikel

RE: Glowing cat
Maybe the cat is clogged and the excessive exhaust pressure is causing it to glow red. There was a car where i suspected that the cat was clogged, the exhaust manifolds glowed red after a couple of min of idling.
