Nothing to clean the O2 sensor with atm, but i replaced the throttle body ( (didn't know i had a brand new one lying around).
Runs virtually the same.
Anyway, saturday i'll go to the bone yard and pull some o2 sensors, if that doesn't fix it i'll try a whole new dizzy, injectors, and fuel filter.
this pos is costing me

I am by no means a toyota tech but I have seen cars stumble and go nuts when warm(old saturns love to) when the coolant temp sensor starts giving really erratic readings.
