Dani,

is your O2 sensor ok ? you know how it can be tested, right ?

I mean - if the ECU gets no correct informations - how should
it drive the FV correctly ?

When you push the full throttle switch the FV signal is
set to a constant PWM to ensure a rich startup mixture (temp switch
is parallel to it) and also a rich mixture when going at max speed/full
gas.

Of course the ECU could be defect, too.
Or a wire broken ?

Do you have the possibility to swap the ECU ?

Betreff: [DML] Re: Can someone explain this? (distributor positioning)


Okay finally an update; I just replaced each of these with brand new
equipment: Fuel distributor, CPR/WUR, +4 plugs, 8.5mm wires, Bosch
cap, Bosch rotor, and HP resistor. I've replaced with used
equipment: ignition distributor. I've tested/cleaned: mechanical and
vacuum advance, frequency valve and plug, grounds on both the left
and right side of intake, ground in compartment behind driver's
seat, cold start valve, and the injectors. The problem: my frequency
valve will NOT run continuously no matter what position the CO is
set to; it will not even run constant with the O2 sensor unplugged.
Like this, the car will start up after a nights rest, but warm-up is
rough with lots of black puffs of smoke and rough running until
warm; once warm it will be sluggish accelerating, but runs smooth
and gets me to where I need to go. The ONLY way to get the FV
running constant is through the full throttle switch-I jumped the
switch by putting a wire to both contacts of the full throttle
switch; this is how I've been running the car. With the FV running
constant, the car starts right up after sitting overnight with about
30 seconds of slight rough running-and has the acceleration it
should. Since the FV runs when the switch is tripped it's obvious
that it works and has good connections going to it. What I am
wondering is why it won't run constant otherwise?Any ideas? -----
