ok so i bought this car a couple weeks ago now and i have about had it with it falling on its face i cant even drive it. ive checked the fuel pressure and at idle its 37 psi but when i go out on the road and get on it. it it falls to about 13-20 psi ive changed the fuel filter that was nasty. the person i bought it from ran rubber hosing for fuel line so i bought some steel line and was going to change that today but Michigan decided it was going to rain so i guess could it be the fpr or fuel pump idk im lost here please help. what are the two vacuum lines at the right rear corner of the plenum one is for the fpr whats the other one for cause i pinch it off and the car runs so much better
