4 cylinder: one air-fuel sensor (on the pipe after the manifold) and one oxygen sensor after the catalytic converter
6 Cylinder: two air-fuel sensors (one for each manifold) and one oxygen sensor after the catalytic converter.

dont look for air when the car cuts out its most likley spark or fuel when it cuts out ranomly its usually a sensor or relay that is faulty check fuel pump relay and camshaft or crankshaft sensors but first narrow it down to spark or fuel if possible also if check engine lite is on check codes

SOURCE: Check engine light
Sometimes can be prematurely dirty air filter, sets off the air flow sensor, which sets off the o2 sensor. So might try new air filter first and erase codes and then see, before you spend more bucks than you need; then if codes return, do the flow mix sensor.

since that is a Boxer engine it will have one O2 sensor at the base of each exhaust manifold. and since it is newer than a 1996 it will have one or two more O2 sensors behind each catalytic converter so you will have three or four ( O2 sensors) fuel air ratio sensors you need to check if you are having a problem. the two at each exhaust manifold are the upstream and the ones at the catalytic converters are the downstream. hopefully that engine only has one catalytic converter going into one exhaust pipe. the exaust manifolds are under the engines cylinder heads (under the engine).
