Coil Pack screw broke off
 

Dear Listmates. I own a S14 with a S13 SR20DET. Yesterday when I went to change the spark plugs, I realized the screw holding the hose spout of the coil pack (sorry, don't know the correct terminology) which connects to the spark plug broke off. The tip of the screw is in the valve cover and I'm going to have to figure out a way to drill it out. Do you think not having the screw to hold down the coil pack down have been causing the spark plug to misfire? Any input is greatly appreciated.
