a bad injector can cause a miss, you can listen to each injector with a stethoscope. It should make a rapid clicking sound. If it makes a deep thumping sound it is likely bad. also an intake leak can cause a miss at idle. also an EGR valve partially open can cause miss at idle. I always check cylinder compression when replacing plugs or coils for a miss. You need quality tech to check for above items.
think its time to remove the head and renew the gasket ,also remove the valves and renew the seals and gring them in a bit ,maybe even renew the valve springs ,or buy a newer vehicle as its nearly 20 yrs old
Check for missing/ broken vacuum hose. Remove vacuum hose for brake booster and plug That checks for air leaks in booster. Check for power to the idle solenoid unit .If that is not working the idle circuit of the carby is shut down. Adjust idle mixture screw as well.
you got it . it is more than likely you have vacuum leak . to chek use a propane torch and while idling intoduce propane at possible area(intake gasket, egr valve , brake booster etc) if idle speeds up and smooth fix it.
