Subject:Low idle, hard cold starting
From:Geza Polony

Hey all,

I have another exasperating cold start/idle problem with  my '84 1.9. Cold
starts hard, with RPM dropping to very low or zero and engine stalling if I
don't keep revs up to 2500 or so. When warm, idle will drop down to 300,
then back to around 900, sometimes stall.

What it ISN'T: fuel pressure regulator, fuel filter, bad compression, idle
stabiliser, plugs, wires, dist. cap, rotor, vacuum leak, AFM, throttle body,
low battery voltage at startup, aux. air regulator, bad ground, Temp II
sensor, O2 sensor, cat, muffler. All these have been checked or replaced.

Guesses: Hall Sender going bad? Fuel pump bad? (buzzes, but car runs fine at
high speed.)

There was a coolant leak at the left head before Bar's Leaking it. One plug
(#1) showed signs of ashing up.

There's a small exhaust leak someplace.

Red alternator LEDs are on when starting/up to 2K rpm. Charges fine (13.9
volts @ idle.)

Thanks for any help you can give me on this one.
