[V8] Low RPM Stalling/Fowling Plugs

[Torrence Thomas (Mobile Office)]

Well the Grinch of Cold has gotten to my V8q.

Can someone point out some obvious things I may have missed.

Symptons: Car starts, but won't hold idle/stay running under WOT range 
rpm's. I can hear backfires/misfires under the hood
when giving it the gas, and unless I hit the gas and rev up to 4k rpms, she 
dies. And I haven't even left the garage yet.

No codes. FPR replaced over a year ago. O2 replaced couple of years ago. 
Now it's stitting in a place with a lift under her (My pals Toyota/Lexus 
shop), so I can get to the hard places. Plugs were fowled badly. Put a new 
set of Autolite 103's in and she ran and idled fine for days.

Took her out made a hard 40 mile r/t run, put her back in the garage, went 
to fire her up last night and got all the above symptons.

Is it the RPM/Speed/Ref sensor twins? Faulty FPR? Restricted air flow? or 
just the Grinch?
Any idea is worthy of checking out.

May the holiday's be good to all.
