Sensor takeover from open to closed loop

[toddbroussardco]

What sensors take over once close loop occurs???I am having a sputtering/stumbling problem as soon as the loop closes(160 degrees).. The car runs great till then...Thanks,Todd

I found the problem..Read some old post about checking ecm wiring,etc..I rerouted the red ecm wire by the battery.I think it was grounding out..Will look for a nick in wire in the morning...Todd
