I've been getting a check engine light blipping on and off. Usually it's when I let off throttle it will flash for a sec. Today it flashed while on throttle and I had a little power loss. Does that sound like Knock or O2 sensor? I'm buying a code reader/resetter, will that tell me what's wrong? S50 has 2 knock sensors and 2 O2 sensors right? I might just replace them all since i don't know when they were last done.
