Sounds like a timing problem or injectors. Check the timing marks and check the rotor under the dist. cap to make sure it hasn't lost the set screw and is wandering around. Check injectors. Listen to each one with a stethoscope. Best way is to get a non contact infrared temperature gun and read the temps at the exhaust manifold of each cylinder outlet pipe. Anything running significantly cooler is the offending cylinder that is causing the miss. Pray that it's an injector and not a burnt valve. Try giving the injectors a few whacks, while engine is running, with a socket extension and small hammer to see if anything changes.
