84 Cat Problem?
After finding the temperature was fine with my 84, I drove my 84 to work today. About 20 miles into the commute, I lost just about all power. The throttle was almost pegged and I was going nowhere. When I got to work which was about 5 more miles, the car would not turn off when I turned the ignition off.
After about 5 minutes and an act of god did it turn off. I started the car about 3 hours later, it just does not sound right, kind off like a hissing noise.
I placed my hand over the muffler and and feel no output. I think it is the cat.
Please help.

If you felt no pressure when you put your hands on the exhaust tips....must be either cats.....or a faulty muffler.....
What are you using???
How many miles did you say????
Check it...something is plugged...I know you figured this out but putting my 2 cents in...SORRY!!!!!!!!!!!
You know just a thought....but if the cat is that bad it will probably be easier to gut........Right????
Hope this helps..

Re: 84 Cat Problem? (oldace84)
When mine did this I gutted the cat. BUT, find out why it failed. nine times out of ten, it's caused by a rich mixture. Check for codes. Likely the O2, MAP, or coolant temp sensor (front of intake manifold) has failed. You will want to correct this problem...soon. Besides ruining the cat, it wastes gas, washes the cylinder walls, dulutes the oil, and causes havoc in general. Good luck, and...
