Default what will happen if i run without oxygen sensors?

i'm waiting for my o2 extension, since i tried splicing and extending and my mickey mouse job didn't cut it so is there any consequences ?

i'm running a pretty big cam and my pcm is tuned!

this is only for about 5 days max .

Don't worry about it. I don't have mine working anymore. I ruined them using leaded gas. My car still runs very strong. It might mess with the daily driver type stuff though. I am race only though. The only thing is that it might make the car run in open loop longer or never go into closed loop. Maybe a more knowledgible person can confirm or tell you I'm wrong.

Sorry can't be more help.

My car misfire and maybe the O2s are making the problem.

Can I try to take away the O2 sensor to see if it will be better?

All 4 of them or just the 2 after the cat?

How do I take them out, is there some electrial socket on them that I can take apart?

I know that the 93's will go into closed loop with out the O2's. Because i tried that on my car. I think if you have got the 4-wire O2's it will not. Not to sure. All I know is that mine still went into closed loop with them removed and it ran like crap.
