Hi.
After replacing a lot of things that can cause a rough idle ( ignition plugs, distributor, injectors, rotors... checked the intakes, gas pressure,etc,etc ) i think i have just found the root cause...
According to this ...

my understanding is that resistance ( in ohms ) between pins 6 and 8 must be about 2,0 KOhm +/- 800 Ohm...
DK for cylinders 1 to 6 ( the DK at the drivers side ) , shows 3,3 KOhms... ( this is the engine side with less smoke from the exhaust..) while DK at cylinders 8 to 12, shows 2,1KOhm... that looks fine to me...
Do somebody knows if this is correct, and DKs resistance between 6 and 8 should be the one in the previous lines ( 2000 +/- 800 ) ?
Thanks
