Loss of power
Car seems like it's lost 75hp over night.
Not nearly as fast, exhaust is not as loud. No sputtering though, still revs up smooth and starts fine, idle is good.
I'll check the fuel pressure tonight for starters. fuel pressure regulator maybe? it should be in the 40 range at idle? what about WOT?

So after checking fuel pressure, it is 41 when the pump primes, however it was about 38-39 at idle.
i also noticed the vacuum line connecting to the regulator smells like gas. pressure went to 49 when i removed the vacuum line to simulate WOT.
should i go ahead and replace the regulator?

so i think through some stroke of genius i've figured out why i've lost power. i noticed i now have a pretty loud exhaust rattle ever since i lost power.
exhaust rattle + quieter exhaust + engine seems like its choking = too much back pressure which means my cat took a ****.
ill take the cat off and see what happens
