I did something really dumb. I went 4 wheeling in a very dusty enviroment and completely forgot about checking my air filter. I somehow managed to get dirt and dust all inside my carb. Well the bronco ran fine the day i went four wheeling and the day after, but when i cranked it up today, it barely ran. i have to give it gas just so it won't knock off and it smokes out of the tailpipes. i took the plugs out and inspected them. they indicate that the engine is running rich. this is a fairly new 351HO engine with very few miles on it so i know its not worn out. i sprayed some carb cleaner down the carb figuring it would help some and it did... but not much. A friend told me that my cat's are clogged up... do you think that's whats wrong? This is my daily driver and its not in driving condition the way it is now so any help at all is very appreciated.
I would also agree that it could be your cats or at the very least some part of the exhaust LOL
