Honda Repair: 93accordlx eng. dies, smog test, o2 sensor

Question
just realized yesterday i negelected to tell you the exhaust manifold is cracked. could this be the cause, in part by affecting the O2 sensor or?

Answer
Chris,
Well you found the answer why your car failed SMOG test! A cracked manifold will cause this all day long.
That should not make the car die. It will cause the check engine light to come on, and could cause the car to run bad but should not cause it to stall.
Thanks
