Before I installed the O2 sensor the CEL would come on around the same time it does now. But, before the install of the O2 sensor it would bogg in first gear, then run fine.

After install, CEL would come on and go into limp mode.

Both times I could not check the code b/c it goes away when I turn off the car.

May be I should switch the 2 black wires... but I dont want to risk frying the ecu...?
