My wife has a 2002 Chevy Blazer that is coding for a MAF sensor. What impact does this part have on the running of the car? Can it fail and cause the car not to run? Thanks and Happy Holidays to all.
MAF sensor code on 2002 Chevy Blazer. Car runs fine since I changed the
fuel pump. Check engine light went out after the work was completed, but now
has come back on. Do I need to change the MAF sensor, or is it unimportant?
