Hey guys I'm kinda few to posting on here and not sure how to search very easily and I can't find anybody with the same problem. Ok so my check engine light came on then off then on and now off. My car sounds a bit different and super slow. Acceleration is horrible. I brought it into the shop and no codes come up and they don't know what it is. A while back I brought my car in and a code for a crank position sensor and he said it was probably an old code. And he cleared it. I think that could be the reason but there's no light on now and it's still has no power. Please help should I replace cps sensor?

 

Symptom sounds like a possible bad mass airflow sensor. does the car seem to rev up slow, even in park? You can try taking it out and carefully cleaning it with brake clean or electrical cleaner, blow it dry with your mouth , it you have an air compressor BE GENTAL , but to be honest I never have luck cleaning Nissan mass airflows, they usually need replaced.

 

I would be it's a crank sensor.
