I assume you removed the fuel pressure regulator solenoid, in which case, you need to go put that back in. IIRC, that solenoid drops fuel pressure while hot to prevent problems with hot starts.

hypnty,
my experience is from 86-88 NAs, that's all I can claim expertise in, and according to the 86-88 FSM, 4A-67,checking fuel line pressure, disconnecting the FPR from vacuum should send pressures UP, not down.
I'm at work, and don't have time to research all of this, but that's my understanding of how this works. I could be wrong, or it may be totally different for turbos or S5s.

Either way, I have mine connected straight to a vacume source and don't have any hot flooding probs.

That's a good line of thinking.. I guess I was thinking he had it capped, like I do..
Sorry, nevermind

i have the same sumptoms on my bare block. Runs like extreme ****, misfiring and all on a cold motor for the first 5 mins of driving. Alomost seems like a blown motor when its really cold. Then its fine.
On hot start i have to use the fuel cut switch or else it wont start.
I have the same mods pretty much but S5 motor, and no SAFC.. and none of the porting.

I would say there might be a hairline split in one of the injectors, or they're leaking through the O rings, or something to that effect! Just saying out of personal experience.

It might be injectors... hard to say. If you shut it off with the fuel cut switch, will it hot start with the switch on after? It should if its leaky injectors.
On hot start, it kinda catches for a split second and then dies and doesnt start.
Would leaky injectors explain the shitty running when cold?
