6 possible causes, already had new O2 Sensors, so
Tried a inexpensive MAF,
So far so good 125 miles and no more check engine light for code P1152. worth it , DEFINITELY.
I would recommend it.

After I installed this MAS and clearing my vehicles computer I carefully did the “driving reprogramming” that was recommended on a YouTube video and not only did it fix my hesitation problem my idle speed dropped from 750 rpm down to 600 rpm while my miles per gallon went from 17.5 mpg to 18.9 mpg. I could not be happier with this product. I hope I don’t ever need to but I would buy this mass airflow sensor again.

Andres Rivera Oquendo –
It didn’t fit perfectly into it’s mounting place but it turns out the mass airflow sensor was not the problem. Can I return the item?
