Ford Ranger / B-Series :: Sputtering / Rough Running Situation Once Warmed Up

'86 Ranger, 2.3L, Automatic transmission.

Been having a sputtering/rough running situation once warmed up, replaced every so often with open loop smooth running. Lately, have had several occasions where the truck stalls and will not restart after a hard right turn (fuel pump powers up, tho) After 30 or so minutes of repose, truck will restart and run.

Recent History:

During the last 1-1/2 years, had cylinder head rebuilt and reinstalled. Had to run it all winter w/o EGR tube attached because of bad fitting at exhaust manifold. Replaced the fitting last spring and replaced cat back exhaust system. Had manifold hole plugged with pipe plug all winter. Have had a diagnosis of poor compression in the past, have not rechecked compression since head rebuild, but did have a noticable increase in power.

Have checked base ignition timing and it is correct. Valve timing appears to be as it should be. Have not had the opportunity to check for spark during one of the breakdowns, since I had no tools and it was night time.

The codes:

Early in Fall, got 14, 21, 24, 34. The 14 particularly interested me, as it suggests ignition problems.

Just before pulling the distributor, I checked codes again; 14 had disappeared as did 34 (EGR issues I resolved above) but I still got 21 (coolant temp out of range) and 41 (no HEGO switch) So I left the distributor alone and replace the HEGO sensor and cleared codes.

Last code check, just got 21(coolant temp sensor voltage out of range) and 24(air charge or Vane air temp voltage out of range) There is very little heat on cold days, full radiator and I've "burped" the cylinder head on an incline more than once chasing trapped air.

I'm suspicious of the TIF module, since the stalling is after warm up and self corrects. It was replaced once perhaps 12 years ago.
