Ok, if i would disconnect my o2 sensor, shouldnt the engine not run right??? because i have left my o2 sensor disconnected and nothing changed....i didnt get no codes neither.....and im running a chipped computer...

 

not always. alot of ppl run no o2. may get worse gas mileage but usually wont hurt anything. i dont run one. it also depends on the ecu.

 

ohh ok just wasnt too sure on the whole situation. thanks...
