Surely he would have noticed a lose plug...... 
Besides, I've never had a spark plug become lose ........

If there's a spark plug that came off, it makes that exact sound whether it's getting spark or not. although if he took off the coil and felt it tug off of the spark plug, then that's not likely it.
