89 fj62, stock 3fe.
I had my truck running great, but it was starting slow. I decided to replace the fuel pressure regulator, since it hadn't been (based on its looks). I put the new one in and started it up. Fuel shot out of where it sits on the fuel rail. So I took it out and the o ring had snapped on install. I checked the pieces to see if any had fallen into the rail, it seems none fell in. I replaced the o ring and installed more carefully. Started it up and now, its running worse than ever. Chuggy idle, loss of power, hesitation galore. Any ideas? I'm desperate to get her on the road!!!!!!!
