Will a missfire cause your car to fail the smog check?
I'm not sure what is checked during a smog check. In the UK we have an emissions test. If the vehicle (petrol engined) has a miss fire it will bring the carbon monoxide level down. But in doing so The hydrocarbon level will rise. That will cause a test failure

What is a car smog?
smogging a vehicle tests the amount of pollutants in the exhaust fumes, verifying the amounts of hydrocarbons and unburned fuel, in accordance to the state in which you reside, assuring that your vehicle is within the specifications of the EPA regulations. Failure of this test is detremental to the registration process. an "exempt" status may be the alternitive to passing the smog by repairing or tuning the vehicle with at least $250.00 towards passing smog test, and another smog. Failure of this test ( with financial and physical proof of repair ) will deem this vehicle exempt for one year..(at least in the state of nevada) good luck to you my friend, JM

Can automotive smog test tell you if you have a bad wire or spark plug?
A smog test may indicate that one or more cylinders is not firing, but it will not tell which one or the cause. An error code in the computer may narrow it down, but it will generally only point in a direction, not a specific thing. If the vehicle is equipped with an OBDII Engine management system then A defective spark plug or spark plug wire will usually cause an engine misfire which will usually set a stored code, depending on the severity. A misfire will cause higher emissions that will show up in a smog test but the failure results will not specificially pin-point the failed component. Many instances of engine misfires and smog test failures can be due to the OEM spark plugs have never been replaced, especially if they have > 60,000 miles. Many times I have corrected smog failures due to mis-fires with spark plug replacement.
Does the buyer or seller responsible for a smog test?
