Re: WOT Huge Power Loss :: Can The Catalytic Converter Cause This?

LOL yeah, I think right now my pimp level isn't very high... The car needs a good washing. lol... and also my radio isn't working propery. lol

If you follow the fuel line going to the fuel rail you should find a shraeder valve (like the ones on your tires but a little bigger). The FPR is on the fuel rail, but you can't check the pressure using it.... To check the fuel pressure you would have to get a fuel pressure gauge with the right fitting and attach it it to the shraeder valve, then tape the gauge to the window and go for a drive. If it's the fuel pump, you should see a big fuel pressure drop when you go WOT... There is a certain range that the pressure should be at all times... I don't know that range offhand though... Something like 50-60psi... but that's just a guess. Maybe someone will chime in with more solid figures. It should be in the FSM.
