i checked for vac leaks and didn't find any. i had taken the plugs off and only found #5 darker then the rest.
and as for the injectors. made sure they were seated pretty good. still missing bad. whole engine shakes but when i rev engine some seem to almost go away but you can tell the miss is their some yet.
