I just recently finished installing my headers and I sprung a exhaust lead on the drivers side header. It sounds like crap right now, but my question is would it hurt my car if I drove it with the leak untill I get it fixed?

it run to its potential but its not really hurting anything by having one

 

won't it screw w/ his o2 readings causeing him to run rich?

 

yes it can and probably will. like i said it wont run to its potential but it wont hurt anything either
the pcm will be trying its damndest to compensate for the extra air from the exhaust leak by dumping in more fuel, mpg's might suffer a tad and it might smell a lil gaseous
