Excuse me Sirs. This interesting threadid sounds like relative to
my problem.
In my 190 E, 2.6L, 1988, I have instaled and calibrated the new
POT, new O2 sensor, new OVP, New Breathing hose for ICV, new
Injectors, new plugs, new hex key repair kit, new vaccum hose,
cleaned the air flow meter and plate, cleaned de IDLE C. Valve,
new EHA, new throtle switch, however I get 90% when contact
the DMVM positive lead to the Pin 3 and Black to Pin 2.
But only contact the positive lead to PIN 3, without contact to
ground the DMVM Black lead, I get only Duty Cycle 36% to 42%
but never 50% adjusting the hex key 3mm.
Please, what is wrong?. Also the RPM is 800 at 80ºC at the
begining and fall till 400 one hour later.
Thanks.
