my camaro (1987 carburated 305) is running extremely rich (smoking black), has soggy throtle response, and gets like 10mpg. from some of my research this may have been as a result of the previous owner messing up the emissions system. i have no cat and i may be missing an o2 sensor or sometihng. could the messed up emissions system be causing my all of my problems?? and if so, how do i fix it?? thanks for your help.

 

it doesn't sound like emmision problems to me,sounds more like a screwed up carb flooding.i don't have my o2 senser hooked up and nothing changed on mine.see if y9ou can get another carb off someone and try that

 

so you lost your o2 sensor and it runs fine???? then do you think that it could be my choke? cause that was next to check out on my list.

 

thats probly it.my o2 senser is there but no wire hooked to it,car runs mint.take your choke and clamp it open with a close pin or some wire.i have no choke on my car either,never liked them.3 pumps in the morn and ready to start

 

this may sound kinda dumb, but are your A.I.R. system/accessories hooked up???

 

whats A.I.R? i disconected all my polution gear and emmisions stuff when i had the motor out.

 

you got a carb problem

 

ok fellas, Z28er lives in Canada. He probably has a non-cc carb. He can do whatever he wants and it'll run peachy (haha, jealous much guys? )

Impaled - what carb are you running? If it's the stock computer controlled setup, your symptoms scream no O2 sensor, now that you've admitted that, get 'er fixed! Then look into choke.
Getting any error codes?
