I keep getting P0131 "low voltage bank one sensor one" Has anyone ever seen this code before? How do I fix it? keep clearing it, but it comes back after no time at all. Thanks.

I'm having issues with my bank1 sensor1 02 also. I'm getting that code and po135(I think) B1S1 insufficient switching.
Have you messed with your exhaust on that side recently? I fixed some leaks on that side and it started right after. I think I'm going to have to break down and get a new 02 sensor.

rockauto.com seems to have the best prices on AC Delco sensors. 51.79 for that one.

No I haven't messed with it. I did put my wideband sensor in the rear bank passenger side. Do you know what side sensor one is on? I wonder if these codes screw with performance at all? By the way how is your truck running these days? Still like that converter and flp? I really need to get one.. but I am pondering getting a new ss and going turbo.

That code is for driver side before cat sensor.

When the code has been thrown, it puts the truck into open loop until you clear it. In open loop you run richer at part throttle (bad gas mileage). It wouldn't effect WOT performance though.

The SS3800 ROCKS with the ATI charger! I put on the 3.6 inch pulley and did the 3800 at the same time, and gained a full second in the 1/4 (g-tech). Track's closed until spring.

The FLP is holding up well and ROCKS also.

The 3800 is stalling at about 4100 on a 4wd launch, and my rpm's only drop to 5000 on a 5900rpm shift point. No waiting for boost to kick in with this converter.

What is your AFR these days? I am running right about 12:1 or so. I would like to lean it out a little more, but the roads are icy and there is really no place to open it up. Good for gas milage I guess. I saw 17 MPG on 92 octane the other day. That is good for me.

Yea, I would really like a converter. I know that it makes all the difference. But the FLP is so dang expensive.

Don't blame ya on the turbo SS!

You still running the stock stall? To be honest, the change from a stock stall to an SS3800 with an ATI would be way better than the change from NA to ATI charged.
These ATI's benefit soooo much from a big stall! IMO a TT3000 is just not enough with the ATI for max performance.

Are you still running the 4" pulley? What kinda lb/min readings are you seeing at top rpm?

Black Blown 02

I'm right at 12:1 from 4000-5900. I wanna stay on the safe side, so thats lean enough for me.

I never did get to logging maf. I was just getting my AFR set when the roads got slick this year, so I dont know how much power I am making. I know that it is a blast drive, and as long as I am moving a little, I can roast almost anyone on the street up here.

I just know that my tranny will break as soon as I launch if I get a converter. Everything that I buy, I want to be able to swap to my next truck. I think that there is enough of a weight differece between this truck and an ss that I would probably want a different converter anyway. I think that that PYE3400 is probably the way I will go. Parish seems to like his.

By the way, what is your pe delay? did you kill it altogether, or are you going into enrichment at like 40% tps?

Black Blown 02

Yep, 40%tps. That seems about perfect to me.
