88 lx 5.0 needs help!

I have an 88 lx 5.0 hatchback, 5 speed tranny. Stock except for bbk shortie headers, bbk cold air intake, accell ignition and wires.
Two days ago the stock fuel pressure regulator blew, started pumping gas through the vacuum port, straight into the plenum. Motor flooded out and died instantly, since then I replaced the bad reg with oem part, turns out it was a new BAD part, put another one on today, it works fine, but now I have a dead miss, sounds like at least two cylinders are dead, no knocking, no rattling. Doesn't sound like a bent pushrod, changed plugs before I put the first replacement reg on, haven't pulled the plugs back out after the second new reg was put on though. Any thoughts would be great.
If you need more info about the car just ask, I will tell all I can, only had it about a month, not sure about much history with it, but I will share all i can.
