Hi, At the weekend, my vauxhall omega 2.0 DOHC 16V started cutting out frequently when stopping at junctions/roundabouts, but only when the engine is warmed up. The idle control valve has been replaced quite recently to stop uneven idling which it cleared OK. I tried the "paper clip" approach to see what error codes the ecu produced, and it listed 12,73,93. For siemens simtec 56.1 ecu
73 is described in various www sites as mass airflow sensor voltage low or mass airflow temperature sensor low. 93 is hall sensor voltage low. Do either of these sound likely candidates for the problem I'm describing or should I look at something else ? Cheers TonyB- posted
