89 toyota supra non-turbo having issues

Cat's don't cause or eliminate smoke.

I'd start with a compression test, checking the coolant for any murky discoloration or oily skin and check for chocolate pudding under the oil cap. Could be running excessively rich but that's more than a bad O2 sensor will generally cause. You're probably smoking while moving too, it's just getting thinned out and you don't see it.

Oh, and oil color means nothing.

i was thinking o2 sensor but i wasnt sure.... this car is all original so i hope i can fix it... i hate to junk it since it all there and doesnt even have rust and the top comes off ...so i hope i can fix it....thanks guys any other ideas??????

ok i put the o2 sensor and i ran it for 20 minutes and its till smoking black smoke but it seems to be less..... could it be that it still needs to burn out the crap in the muffler from the old sensor that wasnt working? i hope so cause me blood is running thin with this car....please respond with any ideas tyvm

Wishful thinking isn't going to fix the car. Check for diagnostic/error codes (see the FAQ section for details) and then the rest of my suggestions are above. Good luck with it. ciao

are you saying your check engine light is broken? so you are unable to read any codes that might flash?

or are you saying your check engine light is not on so you don't think your able to pull codes.. if its the latter then that has nothing to do with it.
run your diagnostic and see what your check engine light flashes.. trust us.
