Oh, didn't know AC Delco still made 3800 MAFs... But, from everything I've read with people having issues it seems the new (must be non-AC Delco) MAFs usually cause more trouble than their worth, and a known working used MAF usually has better chance of, well, working.

But, I'm no expert. I'll look into things more before giving advice in the future.

EDIT: Wowzers, new AC Delco MAFs are not cheap... https://www.google.com/search?q=ACDe...tbm=shop&spd=0
