[s-cars] 1.8T coil odd behavior

[Varon H. Fugman]

How long does the heater in the O2 sensor operate after startup?  Does the
ECU control this?

If there is some common wiring between the +12V to the coilpacks and the O2
sensor heater, is it possible the coilpacks are seeing a voltage drop while
the O2 sensor heat is on?
