5.0 swap o2 sensor heater issue.
99 Mazda b2500 5 speed. Swapped to 2wd 5.0 1999 explorer with 4r70w. Things not swapped into Mazda> cruise control and cats. Things not installed, no egr and no rear o2 sensors. Sniper tuned.
Idle surge after warmup.
only codes p0141 and p0161 is for both upstream o2 sensors heater circuit malfunction.
Only EVTM I have for explorer is for 1996 and doesn't have much detail on o2 sensors diagram
