FTC goes to 20 when stopped in gear?
FTC goes to 20 when stopped in gear? When coming to a stop the fuel trim cell changes to 19 when almost stopped then goes to cell 20. When it hits cell 20 the stft and ltft all zero out and don't move. It stays like this until an off idle condition is present or move shifter into neutral or park. After moving shifter into park or neutral the fuel trims will start moving after about 2-3 seconds. Other then this the car runs great. mods are below.

Plot thickens.
I have figured out that it goes into open loop when shifted from park/neutral to D4 D3 or D1. Reverse or D2 it stays in closed loop. Does anybody know of any way the loop status can be linked to the gear selector?
