any codes?

like p0300 or from what u say p0301 or p0303

random misfires is 300 and 301 & 303 are cylinder 1 and 3. maybe regap the plugs to .35? as you just did the plugs.....maybe the plugs need to be step 1 colder

i was thinking u had the lsj soooo what i said maybe a little different for the lnf. the codes no but the gapping

You can have many misfires before throwing any codes.. There's a timeframe along with how many misfires that can happen. All engines will have misfires.. No such thing as a 100% correct burn

A few misfires is normal. After 10 in quick succession is when you know you have a problem.

I get 1-6 of them occasionally while cruising down the highway. It occurs when I get back on the gas after letting off because of going down hill.

Are you experiencing similar? If so there's nothing to worry about.
If it doesn't throw a code I wouldn't worry.
