700 rpm rough idle. when cold really rough when warm its better. reason to me is its hotter to burn the gas. ordered a new 02 sensor. it looks org. lots of black smoke when cold. (rich) new plugs cap rotor wires. I change them after replacing head gasket. ran changed again and they were black with soot!!!! really rich.


many thanks
