      See Bentley page 5-9, Fig. 4-1, top left item in the pic.

      It's a reservoir.
      Some say it's also a filter, I can't comment on that as I don't recall ever cutting one open.

      Idle air bypass adjustment should not change the duty cycle that much. Something else may have gone awry in the meantime.
      I'd suggest TESTING the oxygen sensor voltages, V-ref, duty cycle response...

      Ok, I can do that.



      The "Fuel injection power supply relay" is pretty simple, needs very little to make it work, has two power outputs, one to the OXS control unit, one to the frequency valve....

      Plugs should be NGK BP6ET or BP6ES. Wires should be NGK (beautiful wire set, matches OE functionality perfectly, better than Bosch) or Bosch. Cap and rotor should be Bosch. No buts, hokay?

      Nope. CSV will still work when the TTS is cold enough to complete the the CSV's circuit to ground.
      HSPR pulses the CSV's ground anytime when the car is starting.

      I'm thinking RG-8X as shielded power wiring to the head unit. I wouldn't expect much, if any, advantage using it as antenna coax. Seems car radio antenna coax uses a series capacitor, at least the...

      While the plugs are out, check compression, cylinders with low readings possibly/likely have bent rods due to hydro lock.

      Actually, that ^ makes just about perfect sense. After-run comes on after running ('d'oh), continues to run until intake valley temp drops to 70C.
