RICH! (The engine, not me) 700

Since it's unlikely to have 2 bad fuel pressure regulators, I'd look for a bad ECT sensor- that's engine coolant temp, on the head under the intake manifold.
If it's failed, or the wire is broken, the computer thinks the engine is stone-cold all the time, and runs like a carbureted car with the choke stuck on.

I'd buy a couple new sets of spark plugs too, to get you through this till it's fixed- you must be fouling them left and right.

I'd also inspect your connection at the Air Mass MEter just to be sure that's not part of the problem. Don't plug or unplug it with the key on.
