i have a 1999 chevy tahoe i noticed i was leaking antifreeze after some checking i noticed it was coming from the intake gasket on the pass side,after replacing both the gaskets and cleaning all intake and plentiun area and replacing the plentium gaskets. i put the entire thing back together.replaced the distribitor cap and rotor plus spark plugs,then when i start it runs real rough and no power. before i did the gaskets it ran very well and no check engine lights were on. now i have a code 300(rapid missfire-random) cleared that and when i go to start it still runs rough as a 8 day clock.. any ideas would be so much helpful right now i am lost and having no idea what it could be.
