Cylinders 3 & 4 flooding, after injector cleaning Options

[tradisrad]

I just got my injectors back from Witchhunter; they slightly improved the flow and the injectors are better balanced (their data sheet).

I painted the injector bodies and let them dry. I had them on a sheet of paper which blew off of the table and dumped all the injectors on to the floor. I could not see any damage.

I installed them and fired up the car, but it ran like crap (it was running well before the injectors were cleaned). So, I started to poke around checking for spark from all 4 wires and it was present. But now I could smell gas and found a puddle beneath my car dripping from the heas exchanger/muffler flange connection on the drivers side.

I pulled the injector 3 & 4, placed them in glass jars and turned the ignition on; they squirted once and did not leak. I then started then engine and it immeditely reved up and the injectors were spraying; it appeared they were pulsing, but with the revving engine it was hard to tell if they were pulsing or on solid.

Cylinders 1 & 2 seem to be running normally.

I am not sure why these cylinders are flood. Does any one have any ideas?
