Have I corrupted this bin somehow?

Im at the chasing my tail point. Not sure if I've got a dead PCM or what but this is frustrating lol.



Car runs fine open loop. An the second it goes closed loop lambse nose dives .750

if fueling is off in closed loop then the o2s arent working correctly

[redtopracer]

Yeah thats what I thought as well, however Im reading proper switching going on in bank 1,1 HEGO

[decipha]

There's a lot going on there that I'm not understanding.

Can you post the log

I figured her out. Hit a raised hump from ruts with the oil pan and k member. Guess it pinched the O2 extension juuuuust hard enough to make the connection screwy.

Would get a functioning O2 sensor every other vibration lol.


So it would show switching, but dump to .00 volts.


Thanks for the back and forth
