Alfa Romeo 164 3.0 12 Valve – Engine management

James Copp-Taylor

Back in the early to mid 2000s, I owned a series of Alfa Romeo 164 3.0 12 valves. The cars were agony and ecstasy, in equal measure. I adored them.

12 Valve Engine Management

  • Uses Bosch Motronic management
  • The Distributor cap is shared with the E32 730 and 735i M30 straight 6
  • Poor idle is down to the idle air control valve, the unit appears to be very similar to the unit used on the 2.0 Vauxhall Cavalier EFi.
  • On the whole, the setup is quite reliable.
