Noticed a slight "miss" during idle and interested in knowing if I should troubleshoot it or just accept it as "normal". Just rebuilt my tranny and while it was out, I decided to freshen up the motor with new V-Power BKR6E-11 plugs , oil, etc. The original plugs where Autolite 3924s (Rocket) but I can't remember if it happened with those though I tend to think so.

It's noticeable twice and slightly a third time in this video...

 

Drive it and see is you feel a miss. Mine does something similar and it is just the large exhaust.
