I have an 01 lt blazer 4wd and 4 door I got the code read and it's po101 pretty sure it's the maf sensor

 

Perfect......now if u do a search for that code there is a flow chart to properly diagnose that code .., follow it to a T it will lead u right to the problem!!! Don't just replace it please.......u could try cleaning it to see if that takes care of it? If not then I would pull up the flow chart...good luck!!!

 

I cleaned everything about 4 months ago and it still kept happening constantly so I replaced the maf sensor which is what the code was reading and it went away and isn't driving rough when I first start it or Bogging out so hopefully this was the perminet solution. Thank you all for your help!
