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

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

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

Is the GIZ2 PCM compatible with this strat?

Decipha you are a saint helping chuckle fucks like me lol

Thank you.

Well you were correct my iscd is at like 40% at idle. Opening the stop screw helped.



How do I go about reducing my iac duty cycle? This shit sticks in my head like eggs on a fresh nonstick.

Car refuses to idle without help.


So your saying that the idle issue isnt related to the tune needing tweeked for the cams?

Like the title says, looking for some input as to what needs to be tweaked to get cams idling ok in a 4.6 2v.


Is it really as simple as playing with idle air/fuel?
