How do you tell if the injector is bad? Just replace it? Would it cause the spark to miss if the injector was the problem? I guess what I should do is flip injectors with the next cylinder and see if the problem moves.

I did forget to clean the spark plug after I changed the dist. cap but I doubt it would make that much difference.

And I also noticed the car stumbles a little more at takeoff than before so maybe its fuel pressure related-maybe?

Thanks.
