Check compression
fuel pressure
spark plugs
sprk plug wires
cap and rotor
injectors

what gap are your plugs? Try widening the gap a little and see if that helps.
too much gap = missing at high RPM
too little gap = missing at lower RPM

Ritz is definitely on the right track....to break it down a little further...
1). Check your fuel filter? If it's old replace it.
2). Check your rubber fuel lines along with the clamps. Make sure none are leaking or bulging...
3). Fuel regulator...make sure you are getting sufficient vacuum to the regulator
4). Injectors...check the harness & wires leading to the injectors. Try gently wiggling them. If your idle starts to fluctuate, it could be a bad connector.
Any of these along with what Ritz & the other poster, (89S13), suggested could possibly cause your missing problem....
Anyhow, hope this helps...
Good luck with the repairs!!
