well it all started a week ago when i went to turn my key to the run position and accidentally turned the engine over like once and shut it off, when i did this my car made a lound sneeze sound thru my cold air intake, since then ive been having idle problems and check engine lights, since then i found out my ECU detected a cyl one misfire, so i replaced the plugs with NGK's bought new 8.5mm wires and replaced the coil pack assciated with cyl 1. started it up still a misfire, you hear it misfiring at idle and when coasting down the road. anyone else have any ideas? im cleaning the terminals right now and if that dont work i think its either the head gasket or vacuum line or something is screw up.......... would appreciate replies

There should be a vacuum line attached to the intake manifold right by the #1 cylinder for the air pump. Make sure that it is on all of the way and the line is not damaged.
