Last night i was driving home after getting my car aligned and started getting on the gas and all the sudden lost power and sounded like my exhaust cracked at the headers. Pulled over hauled it home found out my spark plug was out. Went to the parts store before close bought a plug and put it in. The threads don't seem to be stripped in the head. Now I have a miss when I get on the gas. I wasn't able to gap the plug right last night and i'm thinking about putting new ones in all the way around. I did have to run the car a little after the plug came out to get it on the car trailer. Should the proper gap get rid of the miss? Do I need a new coil or boot? Suggestions for plugs?
