before i tell you my dilemma here is my back story:

swapped the motor (KA24DE) and ever since the first crank up, ive only ran on 3 cylinders, did a compression test and i have 175psi across the board. Brand new spark plugs, brand new z32 fuel filter. All cylinders fired consistant except for cylinder #2, you can take the spark plug wire out, and it will not affect the idle. Ran a test, have 12 volts going to every spark plug and my ignition voltage is normal. Decided to change the injector from s13 obd1 to a s14 obd2 injector. The cylinder still didnt fire. Went back and swapped back the injector #2 and decided to examine injector #3 to compare the two. Put everything back and cranked her up.

now on to my problem:

im running so rich gas is coming out of tail pipe...this is new to me, just happened just now, swapped #2 injector back to the old one (s13 obd1) thought maybe the resistance in the obd2 s14 injector might be a tad higher causing not enough fuel to spray, cranked her up, still running on 3 cylinders...so i pulled the spark plug on cylinder #2 and the car almsot died!! (which is good cause now its firing) But now cylinder #3 is doing the same crap that cylinder #2 used to do! and now i got unburnt fuel and loads of white smoke outta my tailpipe!!

whats the dealio?

its obvious im running rich, but why? leaky injector...bad rubber washer..let me knowwwwww!!!
