Running on one rotor
I've been trying to diagnose this problem for a while...today I decided to check the plugs and saw this.
The two on the left are from the front rotor and the ones on the right are from the rear. Just to make sure it wasn't a spoof I cleaned them and alternated plugs and let the car fully warm up and took them out again. This was the result the second time around.
The exact same thing result, the plugs on the front rotor were clean and none sooted while the rear were sooted. The plugs didn't seem wet and I checked the four wires and spark was coming from them. What could cause this problem? Any help would be greatly appreciated. Here is a vid of the car running...it is obviously running on one rotor, I videoed idle, the boost guage and fuel pressure guage just to give any insight. The vacuum is at 15 on the guage.

Definately check that, hope it is something simple like the plug is not all the way in.
How long was the fuel system open for? The fuel can dry up in the injector causing it to stick. Most times you can un stick an injector by applying 12 volts to it you will hear, and feel it click. If that doesn't work take it out and hit it with something soft. reapply 12 volts.
Hope you get this fixed today, good luck
