This is a 1988 323 gt. Compression is good (~145psi on each cylinder), spark is good. It is running insanely rich, you can actually see fuel leaking from the exhaust manifold right around cylinder four. There isn't any fuel leaking from the fuel pressure regulator when I pulled the vacuum line off, leaving me to believe it is good. I tested the O2 sensor recently according to the manual and it seemed to check out okay. Also, this was an intermittent problem in the past, but is now constant. There is no check engine light on, but this car has a modded ECU. The injector resistance of injectors 1 and 4 (I only checked those ones for now since they are easy to get to) is 14 ohms. With the engine off key in run, injectors 2 and 4 both vibrate insanely. Are they stuck open causing this insanely rich situation?
