Idle checklist
#61
Pulling the IAT connector would make infinite high electrical resistance so the thermister sensor circuit should mimic a low temp reading
ECU connector condition on pins X and Y ?
Dip in P is being thought about as you already looked at the transmission connector
Might be at the point of getting the TPS to match the currently sourced ECU
IAC valve clean ?
EGR valve closed
EVAP vavle closed
ECU connector condition on pins X and Y ?

EGR plunger moves freely and rests closed, was also swapped with presumably working unit with no change.
EVAP can be plugged if needed.

Hmm. When shifting from N to D timing momentarily retards 6 degrees from when the dip occurs timing retards 6 degrees for a split second.
Oh and the missing is back, crank sensor still has original lucas branding so that’s going into the trash very soon...
