Alright cats and kittens, I need the best thinkers to toss out some ideas. I've been fighting a fuel pressure regulator issue for awhile. Car doesn't have 35k on it and I am now going to put on its 4th one. The first happened at around 19k. The ol Man had it replaced at a local shop years ago. It started to fail again a few thousand miles later but at that point it just sat for many years. Once I took hold of it, had a used one put in (as you know, they aren't made anymore) by a GM dealer. Here we are again hesitating under load at low rpms and I'm 95 percent sure it's the regulator.

I can't figure out why they keep failing. It's not a cheap fix every time either. I have to get this one replaced, if I can find one, but what in blazes is doing it?
