Engine takes a long time to rev down

I'm just trying to make sure you have the correct MAF sensor for your throttle body

i little searching tells me thats a 96-98 maf. if your on a 2000 bin file the maf could be the issue for sure.


a 2000 maf http://www.ebay.com/itm/New-Mass-Air...dVcXp3&vxp=mtr

a 96-98 maf. http://www.ebay.com/itm/OEM-GM-Mass-...p2047675.l2557


the number on the top of the maf you posted is the part # for the maf.

and a 2000 maf wont fit right in a 96 tb. so you'll need a 2000 tb as well to go with that maf.
