454cid

So issue is "only" happening going over bumps? Some wire is chaffed, a ground is losing contact or something in that realm,
I'd agree that sounds like a connection making intermittent contact.
if I had to guess. But don't guess. At some point I was going to say that the MAF also has the IAT sensor
The new MAF likely has an IAT in it, but I don't think it's being used. The 454 has a separate IAT in the intake tube. Unless the IAT harness also plugs into the new MAF?
OP, I'd recommend watching this video, and part 2
