and there is no real way to check this unless I replace those hoses on the fuel pump? Ughh...lol. Im removing the cat just to see if that does anything. a lot of people I've talked to about the issue have no idea where to begin with this problem haha

My guess is you have a crack or pinhole in the accordion hose on the fuel pump you aren't seeing. Your fuel pressure should not drop like it did.
I will also suggest you don't drive the car until this is resolved, unless you want to be replacing the motor as well. You are running lean (not enough fuel) and that will destroy an engine quickly.It's stock.

this is what I saw on my pressure gauge when I had a pinhole in my corrugated fuel line.

Cool information...I have 170,000 miles on mine, and don't know if the MAF sensor has ever been cleaned. I will try that tomorrow...thanks, even though this thread is two years old!!!! I'
m having the same acceleration issues as the original post, but with mine, when I depress to WOT, it runs great...mainly it's low rpm hesitation....
