Well, according to Auto Tap, the computer is indicating insufficient switching from the O2 sensors that are located right before the cats!
I have changed the O2 sensors and still the same problem is there.
The driver side O2 sensor connector clip was damaged; therefore, I bought a new connector replacement from the dealer. I had to cut the wires and join them with the new connector.
Could it be possible that the O2 wires must be a specific length?
One more thing! The Ltrem fuel is always maxed out at idle, when I clear the codes it goes down to 18-19 at idle. However, at WOT it is normal.
I am very puzzled! And help is really appreciated!
Does anybody have a 98 computer to test on my car? I have Ed Wright tuning, that could be the problem but I want to make sure!
All mods are in my sig.
Thanks!!!!!

I have the same problem with the drivers side O2. Mine started right after my SLP longtube install. I had the O2 replaced under warrenty but same code. Who knows whats up with this problem. As soon as i get a few extra bucks im going with LS1 edit and taking care of it once and for all. I do know mine is hedder releated.
