I keep getting codes that have to do with the heated O2 bank 1. Does this mean that the O2 sensor is bad and will it cause it to break up under 3/4 to full throtle. TIA

Yeah, replace it with a Denso unit. Probably wouldn't be a bad idea anyhow, depending on the mileage. But, if you're getting codes for it, replace it.

Yea, that might explain why your O2 levels were all over the place in your scan.

Yup, I would echo that idea as well.

thanks for the input. I am picking up a new O2 today and will put it in and let you know what happens. Buy the way my car decided not to start this morning and if i recall yesturday right before i shut it off my O2's on my scan gauge read 0.

Get an ac delco 02 unit not denso.

The Denso unit will tolerate lead better, should you decide to run leaded race fuel. Also, from what I remember, the Denso unit reacts faster, too.

I had the Denso it kept throwing the heated o2 bank 1 code I actually bought two of them and both threw the code as soon as I put them in so I switched to the ac delco no more codes for over 6 months

ok i replaced the O2 sensor and no more codes for that. The car still seems to break up at higher rpm's. The LTFT's are at between -5 to -10 but lock in at 0 at WOT but i can only do that for a little bit then it breaks up. Any ideas on what this might be. The car has a pcm from overkill and i swapped a s/c motor into it. I am using the n/a coil packs and control modual, could that be causing it? I bought a LS1M today so that should be here next week so i can scan it. Also the O2's seem a bit more stable while driving. Help from all would be great, i will try anything to get this running normal.. TIA

I don't remember, but do you have a GTP fuel pump? Your GT/Base fuel pump might not be enough.

A lot of people recommend swithing FPs. I would. On these cars (1997-present) the fuel pump is relatively easy to replace. There's a panel in the trunk with 6 bolts holding it on, that comes off and there she is!

No problemo. Believe me, not having to drop the tank is a godsend!
