A while ago I asked about a misfire I was trying to track down. Tried all the usual stuff to no avail but recently the car wouldn't start and it turned out to be a loose/slightly corroded wire to the starter motor. My question is, could that loose wire be the cause of a misfire? I think it must of been like it for a while and I'm sure someone said that any loose electrical wire could cause a misfire. Is this true and could it be the cause?
