modulation

  1. EGR Modulation Solenoid Valve

    Alfa 145 & 146
    hi guys Im busy fixing up my 145 2.0L ts 96 year model. The previous owner said they turned on the adjusting screw with a Philips head. Is there any way you can tune it on your own without having to go to a garage as this valve helps with fuel consumption. Any help will be much appreciated...
  2. GT ABS pressure modulation rate

    Alfa 147, 156 & GT
    In all other cars I've driven the ABS pressure modulation happens quickly - the judder that you feel through the pedal. In our GT, on the other hand, it's more like on-off-on-off. Normal or not?
