Having a puzzling issue on my 2000 Civic LX. Recently took it on a long trip, around ~400 highway miles, on the return route it threw all four misfire codes plus the crank position sensor codes. I wasn't expecting this at all considering I did not really notice any difference in the way the car was driving. Didn't really notice any hesitation, stalling, accelleration trouble or anything like that.
Codes were:
P1336
P0301,P0302,P0303,P0304.

I'm currently driving the car for the time being and wondering if this could further hurt the car. Hope to take a look at it this weekend. I don't want to just throw a new coil pack, wires and plugs at it if that isn't the problem. It could end up being maybe the distributor or crank sensor or something else ? I figured I would ask the experts here first and see if it is a common issue.

Thanks in advance.
