When I pulled the injector loom 'rail' off earlier, I released the pressure with the nipple and there was a little squirt so theres some pressure getting to the 1st injector. Does the fuel pressure show on OBD2? Never really needed to look into it before, not sure about the fuel filter haven't had the car long enough.

Would fuel starvation affect the ignition timing? Thats whats concerning me the most, as it seems to be bizzare that it wants to advance so much??
