Couple of random questions

[Art-and-Science]

Do a fuel pressure test before you condemn the regulator. You may have a very different fuel delivery problem. (pressure tester costs less than 20.00 at harbor freight, and can save you from unnecessary replacings)

Sounds like you are experiencing power loss under load. Ie your power steering is going during a turn or while you add the a/c load to the engine.

I am far from an expert, but it sounds like a fuel delivery or air intake sort of problem.
Do you have a scan tool? What do your o2 sensors say when you are experiencing a power loss?

Oh, any other codes or recent codes?

I'm definitely planning on doing a fuel pressure test before replacing anything else. Unfortunately I do not have a scan tool :/ the only code I have right now is the low air flow to EGR code (P0401 I think?). That is a good observation, I never thought about the power steering effecting the engine while cornering.. If not the regulator, then what else could be the culprit? Injectors, fuel pump? I have a K&N oil type cone filter on the intake that needs some cleaning, but I don't think it would cause this significant a problem. Plan on cleaning it and oiling it tonight so we'll see.

Thanks!
