Default Misfires

I had misfire in cylinder 4 put new spark plugs and cleaned the injectors with acetone until pattern was nice and spread, however it did not help, its still misfires and dies on idle when pressing gas.

What elase i can look at, i mean wires were replaced also but for used ones from junkyard, it did not solve the problem though, it still misfires, don't feel like getting new wires because i am about to junk the car.

What else can i check, can someone show me correct wiring diagram perhaps they aren't connected properly.

My very distant guess is one of injectors is no good in the way that its leaking (i smell a lot of gasoline in exhaust) i did mark them when taken out initially to clean but i did 1-2-3-4 from left to right and i think in manual they marked from left to right like 3-2-4-1 so i swapped them around and i could have misfire moved from cylynder 4 to another cylynder, if identify what is new cylynder with misfire i can just throw away that injector and replace it it with working one this should fix problem.

Are you saying you used junkyard wires? I wouldn't use junkyard wires even if somebody paid me to.

If you're junking the car - why do you care if it's misfiring? (No offense, just going by what you said.)

I would not junk it if it was driving normally, but i cannot even sell it to anyone when it misfires and hardly drives at all.

I will run multi-meter test on wires according to repair manual today as well as injectors, however i'd appreciate additional info.

Wires. Any carbon tracking on the plugs?
