Firstly, rough idle, can stall when braking, starts well hot/cold,drives with plenty power, bad fuel economy (12mpg?) new injectors, new fuel filter. Sender is not working. Idle will climb when put in P.

Secondly, dragging grinding metallic sound from rear, once in a while, goes away when brakes applied, no leaks. Brakes evenly , smoothly coasts whithout drag, E-brake only engages at very end of pull? dragging e-brake shoes/badly worn bearing? just thinking ahead$ cost$?

Sorry, I'm making a mish mosh of terms. The unit with the hoses and hex fittings is the fuel distributor. The control pressure regulator is in front of the metering unit, near the dizzy.

One more thing: If you have a high idle, the auxiliary air valve may be bad. Stuck open, it would cause a lean, high idle condition. They are problematic at this age.

Hi 3ring. Your grinding out back, especially with the no-ebrake, is almost surely destroyed e-brake shoes. You may even have broken hardware hanging up inside the disc hub.

On your injection issue, sounds like it's time to take it all apart. I would say you either have a problem with the metering unit or the fuel pressure regulator unit is shot. The metering portion is the little metal plate that floats up and down to measure air flow. This is right above the black rubber ...what... sock? that brings the air in from the filter box. I've seen them filthy and corroded inside and unable to respond smoothly. The FPR is a larger and much more finicky unit to break down and repair, but it can be done. They are prone to clogging from all sorts of debris getting through bad filters and such. This is the part immediately aft of the metering unit. Look for the multiple hex fittings on top.
