So yesterday I drove my car out 45min drove perfectly fine, I went to an interview real quick and when I started the car is started idling rough.

I immediately knew it was the O ring on injector #3 because I already had a feeling it was going to go bad considering I pulled all of them out.

Ok so I drove the car home, and it starts acting normal again, I parked the car and figured I'd pull the injector and pull the o ring to replace, of course, the O-ring was in 2 pieces. I replaced it with another injector I had laying around and tried to start the car and it started really rough and then eventually died(flooded in guessing)

The car made a loud CLUNK/BANG/KNOCK whatever you want to call it then I started taking things off and reassuring myself I did everything right. I came to realize that cylinders were flooded with gasoline as I pulled the spark plug cables.

I removed the fuel pump fuse and took the spark plugs out so with compression it could shoot the gas out, sure enough all the gas shot out (lots and lots of gas constantly had to keep cranking".

After that I put spark plugs back in and cylinders #1 & #2 were fine but #3 & #4 kept flooding. Injectors are not stuck open, I have gas, spark and air all working .

I did an oil change and there was a lot of gas mixed with the oil,

Put fresh oil in and now it's flooding again.

I checked ECU everything looked perfect, check injectors , Checked plugs , checked rail , the car turns on but very rough it will not stay on unless I'm feathering the gas.

I need any tips or help I can get at this point. Only thing I can think of is that spark plugs fouled out from the gas.http://uploads.tapatalk-cdn.com/20160309/afec6e16446b5d2bbbe48b9292380e1c.jpg

It might sound like a dumb question, but are all of the plugs the same?

Try swapping them around with the known good ones and see if the issue follows the injectors or stays with the wires. That should narrow down the issue to the injectors or something else.

How are you sure the injectors aren't stuck?

Do what I suggested. That way you'll know if the issue is with the injectors or not.

Have you tried putting injectors 1 & 2 into 3 & 4 and 3 & 4 into 1 & 2 to see if Cyl 1 & 2 get flooded like SoundEfx suggested?

Your fuel pressure regulator may have failed..
