but it don't cost nothin' to check. Next to the fuel pressure regulator, on the fuel rail, is what looks like a tire valve cap. The shrader valve on my and a few other V6's has come loose and required replacement, pop the hood, is there a gasoline smell? remove the cap and look to see if gas is leaking out, maybe this is causing a low fuel pressure situation at high rpm's? Now I'm just making things up.
Other things to check: fuel pressure regulator (not likely to fail, but some reports of failure just after a new fuel filter is installed); vacuum hoses going to it? Other vacuum hoses?
What happens if you hit the gas when in park/neutral, is it rpm specific, or just under the load of acceleration, e/g/, check that the throttle body is not sticking.
