92' Cavalier 2.2L 4 cyl. runs but has a miss coming from #4 cyl.
Ground the valves because of gummy condition and replaced injector. Replaced crank sensor and coil pack module but still it's missing. The spark plug has fire out of the block. When you put it in the block it misses and when you remove the plug it's wet with gas. Help!!! I'm running out of money.

To review - - do you know for a fact the distributor is firing that cylinder? And do you have power and a ground pulse for that injector ?
You say no vac leak, but have you done a compression test on all cylinders ? Is it possible the egr valve is leaking and affecting that cylinder ?
If you know for a fact the injectors are not opening, you would need to check for voltage and a ground signal from the computer. The computer grounds the injectors to open them based on the crank and cam sensors.
Replace the catalyst convertor. When a convertor goes bad, the guts of it break apart and end up clogging the exit port. One of its functions is to remove toxins from the air. Helps the emission system to run rich or lean gas exhaust.
You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.
