My problems are almost the same, once the car warms up it bucks at 3k to 4k RPMs. I was Thinking these could be symptoms of a faulty fuel pump, ECU, and after reading this post i thought maybe the regulator as well. Do these signs show symptoms of either faulty ECU or the fuel pump?

Dude, just replace the regulator. It's easy enough, really! Just make sure to pull your fuel pump fuse first, OK?

Well, hmm. Maybe you forgot to mention a symptom to us that would help? Given what all you told us, the FPR should have worked.

Did you use a brand-new FPR or was it used? Did you check your fuel pressure first as was stated beforehand?

I suppose at the very last thing it might be a leaky injector O-ring...

The regulator was new, I never checked the pressure I just changed out the FPR.

Just recently after I turn it on and let it warm up, not even driving it, it starts missing and cuts off and doesn't start back up?!?!?! Before it would have to drive for a while before it began doing this but it is only getting worse. Other than that I believe all the other symptoms have been stated. It only acts up when it is warmed up that is the key detail.
