Diagnosing a miss?
 

Seems like you can't really hear it in the video, bu twe suspect a "miss" in the engine with slightly loping idle. Can I use a multimeter and see if each plug has voltage going to it from the spark plug wire? Also, is replacing the cap, rotor, and possibly even the ignition coil itself possibly a good idea?

This is how it runs.

This again. Still have not fixed that lower end knock huh?

Two things:

1. I have done a lot to diagnose it. Still nothing conclusive.
2. y resources say it has to stay like that, even if I knew what it was.

Got the plugs tightened up today, runs a little better. Had mega exhaust leak.

my old 95 blazer had this identical knocking sound. it was a cracked flex plate...im assuming this is your problem too if you haven't figured it out already, but im 99.9% confident

My guess is if u pull off that oil pan it will be real easy to find the noise in your lower end!!!

The more I think about it the more I lean towards the damage on the pan being related to your noise

Not to knock this guy, but he does not like to listen to suggestions, everyone has told him everything that it could possibly be, but he will come back in a month or 2 asking what the noise could be

Its been this way on here and s10forum for a bit.

Oh so he's retarded huh???:icon_omg::icon_attention:
