I was told by my mechanic that I need a new MAF sensor. While he quotes several $100s to install, I can buy the part after-market for $250 new, or $50 from a junkyard.
The install itself looks easy (4 bolts off the air handler). However, are there any concerns or worries about doing a DIY, with or without a junkyard part? I see the programming issues listed so I am a bit worried.
Also, what does the MAF really do for me? The car seems to run OK -- it's 188K, so it's a bit rough on the edges. Will it improve fuel economy, or do other things?
N.B.: I also have the "Check Engine" light on, but I am unsure if it's related to the MAF. When it first came on 3 yrs ago, another mechanic diagnosed it as an EGR valve. The current mechanic did not mention the Check Egine light or computer when talking about the MAF sensor.
Cheers.
