Sounds like its running on one rotor.
I have a S5 gxl / T2 swap. I couldn't get it to stay running and it just kept backfiring but I fixed a couple of problems and it runs now.
The problem is it runs really bad. It sounds like its running on one rotor. Compression on all six faces of the rotors is 90-95. I pulled the plug boots off and there is spark to all four plugs. It has a new Walbro 255 fuel pump. Timing is dead on.
Any ideas?

I was thinking along the lines of maybe its a coil problem so I went to the lead coil and check for voltage on the black/yellow wire and I had 12v.
Next I went to the green/yellow wire that is supposed to go from 0 volts to 5 volts as the engine is turned over but I got 0 volts. It didn't change as I turned the motor over.
IF that is true, should it even run? Running on trailing coil only?

The car should not die just from running on the leading coil. I would focus on getting the car running under this scenario.
