I disconnected my o2 sensors and my car runs really good ,is it safe to spray 150 wet shot of nitrous while the o2 sensors are disconected,I have a 94 lt1.

 

You probably need to study up on open loop tuning if you haven't already. You should at least get a dyno tune so you know the best jet combo to run that will not lean it out. Or add a wideband o2 w/ monitor to keep an eye on things.

 

Why did you disconnect the O2 sensors? Was the car running poorly before you disconnected them?

 

the car is running rich,it runs poorly.

 

The O2 sensors give the computer feedback on the car running rich or lean to adjust fuel injector duration during part throttle driving. If your O2's have 50K+ miles, I'd replace them.
