What year is your car?
Some MAF are on the throtle body 2 tork screws unplug put in new about 10 minutes work. Others are inline on air tube to throtle body maybe 15 minutes the 2010,11,12 are on the air box takes 10 minutes to replace. I have replaced 2 MAF on my Olds and 2002 regals used reman from advanced one has 20,000 miles no problems the other 40,000 miles. Might try cleaning the MAF first $6 can of CRC MAF cleaner better than $120 and up for reman or new maf.
