cat problem?
ok, here is the problem, my 84 bronco with carbed 351w runs great for about five to ten min until it gets up to temp and then dies. i talked to some people and i have heard that a clogged exhaust can suffocate the engine and make it die, it has two inline cats on it and as far as i know they are oem. i would take them loose to check for myself but, alas they are welded on. the question is how likely is it that they are my problem?

Tap the cats with a hammer and listen for any rattles. If they do, they are toast. Parts of the cat can also come undone and clog your mufflers too.
If they are going bad, you probably should have noticed performance dropping over a period of time, as they come apart and clog.

I have a buddy who had an 80s dodge with a 4 banger, and the cat got clogged. the engine got so hot it cracked the head, so you should check it out as soon as possible. I hate driving my truck when i think there might be something wrong with it

i am the same way, since my entire exhaust system is welded up, i was thinkin about unbolting it from the header and ramming a coat hanger down in there to see if i couldnt break somthin loose. what would happen if the thermostat i put in is too low a temp?
