94 accord has an an occasional miss/stumble at idle and gets worse when revved up. I just replaced spark plug tube seals and had the valve assembly off to do so. I re-adjusted the valves, new NGK's, new wires. Thoughts?

 

distributor cap hairline crack, rotor gap to wide, coil failing,

 

could be clogged injectors.

 

Ordered cap and rotor, will give that a try first then test coil if it still misses. What does the group recommend for cleaning injectors, remove and flush or any luck with additives, like seafoam?

 

you could try seafoam first and see if it helps at all then go from there.

 

I second Seafoam first.
