305 misfire on cyl 5
 

I am now having a p0305 code which says the cyl 5 is misfireing. I just had a new clutch put in the 97 boxster. Could something happened when the job was done toa cause this? I have not had this issue before the repair.
What should I look for to cause this?

Thanks in advance.

Plug wire got loosened?
 

Coil cap got cracked?

Since #5 is the middle drivers side (US) that would be a bit odd.
