Hi guys,

What happens when o2 sensor is dead?
Will it just cause engine to run rich and if yes would you hammer the engine on drift day when one out of the two o2 sensors are gone?


I am planning to go buxton raceway this sat and realised one of the o2 sensors is gone

I think it was because i heated the exhaust flange to remove the exhaust from exhaust manifold

I know if you leave o2 sensor in place without plugging it in, it kills it due to soot i believe but i thought you can heat it without a problem


Would you change it?
