Misfire?

1989, 5.7/700r4

Stock except for exhaust as far as I know.

Looks like it just had a tune up but cant say for sure. Has what appears to be a new rotoe cap and plug wires. Runs fine but just get this kind of popping noise at idle. Thoughts?

Is one of heat shields at spark plugs rattling ?

Didnt think so but Ill wiggle them around tonight. It just seems like the miss is at the same interval every time.

Does it have a miss,the sound I thought I heard didn't sound like a miss,if you think it's a miss you could always spray your ignition with a spray bottle and then it should be more pronounced or louder and maybe able to see it in the dark,just don't drowned it. And use water

It seems like it to me but I not for sure lol

Well if you have a miss it will be more pronounced in gear, but don't try to ck it by yourself if you try to find it while in drive or reverse , get a friend to help with that

Bleh still tracking this down lol. Took all the plug wires off and tested them, had nothing above 7.5k for resistance, wiggled them around and was still good.
