Is it loping because the idle is too low or is it the RPM bouncing?

Default loping

There are many causes of loping idle. If you keep chipping away at it youll find it.
Vac leak
Moisture in fuel
clogged injectors
Faulting TPS that changes the signal
bad or sticking IAC or dirty MAF
sticking PCV
fuel pressure or regulator
sticking valves
These are some of the more common
coil packs

If the idle is jumping around my bet is TPS. It has happend 3 times now with Ryan (2 times on the Bonne, 1 time on his Jeep). The price Ryan has to pay for having such a clean engine bay.

Marty, haven't you done a TPS mod? And what did the idle do following that?

Severe RPM flucuations.

There are many causes of loping idle. If you keep chipping away at it youll find it.
Vac leak < - No
Moisture in fuel < - Every tank? No.
clogged injectors < - Cleaned, Rebuilt, and flowmatched in Oct. No.
Faulting TPS that changes the signal < New, Nope.
bad or sticking IAC or dirty MAF < Tried 2 IAC'*, and new MAF. Nope.
sticking PCV < New. Nope.
fuel pressure or regulator < Wouldn't cause this issue.
sticking valves < Possible, but you're prolly gonna hear them.
These are some of the more common
coil packs < New MSD'*. Nope

I can honestly say, my old Bonneville and this Bonneville both have never idled perfect.
I have never been able to pin point why either...
I've learned to live with it, annoying as it is

Sounds like a heavily cammed big block. Very lumpy compared to what it should sound like.
