Fuel pressure question - HELP!
My fuel pressure is low after I drive the car hard and I can't figure out why. I set the fuel pressure the other day to 43psi and after driving around for a while, when I return home and check the pressure, I've lost 5 psi and it's dropped to 38 psi.
Has anyone experienced this problem?? Basically the fuel pressure starts out at 43 psi and when I get home it has dropped to 38 psi. If I bump it back up from 38 psi, and let the car cool off, when I start her back up the pressure is at 48 psi, 5 more than when I first started the car. Something isn't right. Should I do a vacuum check?
