Any ideas please, since November 2015 my R33 started turning off when I geared down at intersections to then just switching off while idling in garage cleaned checked and cleaned out air flow meter, replaced with new the fuel pump and fuel relay, replaced Idle air control valve, replaced with new ignition module, checked fuel lines and while it has not stopped while idling in garage when driving its like something sucks the power off and on at random moments and will turn off if your at an intersection if driving and got your foot on it, its more like a surging?? getting really over it and got no engine light or fault codes coming up?? has anyone experienced something similar?
