Dear all,
recently I changed the black E.H.A. Valve that is mounted on the fuel distributor (Bosch# 3.437.010.040) with a brand new original one. After that the car run smoothly with no problems at all and no black smoke. I noticed that when the car is a bit cold it won't start. I was too afraid of the EZL unit but thanks god it was fine. The car will run only if I disconnected the black E.H.A. Bosch Valve wires. I did all what I thing it's possible cause including changing the ABS/ASR computer.

What shall I do? Thank you in advanced : ))..
