Engine runs rough
misfire 3.5L V6
those disconnects, each , will slam the PCM into limphome mode.
you need your own $9 scan tool,
pulling the sensors, only stores DTC codes. that only hide there real ones.
next time you pull a sensor, use the scan tool and reset the PCM.
clearing all codes, then drive and see what fails.
imagine a sick patient in hospital bed and you cutting lines to the person.
you cant fix cars with no scan tool and 100x that , if intermittent.
cant. (i can, but have voltmeters and such that can log data)
running good before, , all cars do that even new. they all run
what counts when its bad.
so connect the scan tool and log the sensors, and see
what DTC pops first. and see all the sensor data.
bank1 OXY sensor 1 heaters is bad. (or wires to it melted)
on some cars , if the heater shorts, it will take out other sensors
here ill look yours up in alldata.com
the heater runs off 12vdc, and the current is monitored by the PCM.
id fix this first, (after all , its bad, fix it)
P300, is all 6 misfiring, that is most likely bad fueling, too rich or way to lean.
the OXY B1S1 short will short the C436 power bus, and maybe
slam B1 full rich,
C436 runs many other things that need power, so if it shorts.
all bets OFF !! all black-yellow wire power feeds.
it runs PCM pin E1, ,EGR, fuel press.reg.sol. , intake air bypass #1 and 2. and screws up altternator pin1 (96 only)
yah, B1S1 , new, and if wires burnt there , fixed.
