2011 Xterra PRO4X manual. 133K Miles

Hi Friends,

My Xterra has intermittent power loss under light/medium throttle. The check engine light will flash quickly then go away. It is very random and can go weeks without a hiccup. I just scanned it and no codes.

I know it can possibly be the crank and/or cam position sensors. I haven't changed them in the 10 years I've owned it.

Question: Would you change them even without any codes? I dont want to throw money at an unknown issue but also dont want to continue driving and end up stranded.

Let me know your thoughts. Thanks!
