If you are running o2 extensions that may be your problem. You ahve to use the corvette rear 02 sensors to cure this

What is the difference between the 02's on an f-body and the one's on a corvette? Have you ran into this problem?

The o2 on the vette naturally have a long wire and i assume the resistances dont change by adding the extra wire

More likely the higher heater wattage on the
'Vette sensors helps them survive and work,
in the colder header position.

Does anyone know if using the vett 02's get rid of the 1153 code? I keep getting this code. I have replaced the 02's and still get the code 1153.

if 1153 is insufficient switching then it may

One (or more) of you long-tube boys with these
heater / switching code problems need to step
up, try it out, report the results and the good
part number(s) so we can make this a sticky if it
turns out to be the cure. 'Cause there's plenty of
the disease.

Any news on the fix for this yet?

I got the P1133 disease and was hoping the Vette O2's may fix it.

Also, can I simply install one of the Vette O2 sensors or do they need to be installed in pairs? Obviously by the code I'm throwing the vette O2 would be installed in bank 1 position 1.

Thanks.

I bought the bosch ones from sparkplugs.com and it cured it for me.

How long have they been in?

I have an 03 vette with LG long tubes and I still on occasions pop 1153 and 1133. So I do not know if 02 sensors from a vette will help you guys.

That code is thrown when the 02 are too "cold" right?

The truck guys had problems with the insufficient-heat thing... it's almost necessary to run ceramic headers if they're anything more than mid-length in the trucks.

I ordered the bosch 13111 to see if I can fix my P1133 code. I'll report back when I get it installed.

I found it on ebay for $64.99 .

I am running SLP LT's w/ cats so my headers are ceramic coated. I'm hoping the elimination of the O2 extensions and the better (?) made bosch will help. Or maybe the bosch will be more tolerant of the envirnment that the new delco that is in there now.

The rear Vette O2s are supposed to be the ones with
the good high-watt heaters. O3SpiralGray, are your
codes coming off the fronts or the back O2s?

bosch are tuff i have a 4 year old bosch in my vw, (89 ford mustang 5.0 "LONG LEADED") $38 at autozone spliced in. Anyways i've run 440cc with the stock programming (AKA chug city) for 3 months, blew the headgasket on nitrous and washed it and the cat, and the bugger still passes emissions and the car gets 28mpg (1.8 8:1 supercharged factory). A/f gauge is highly responsive during closed loop. They are TOUGH cookies.

I may have to watch this thread as my stock o2's are at 72K. I adjusted the MVolt switch point to increase mpg and (thinking if they are getting older, less mvolt response, may help them).

Hptuners shows a great warmup and good swing value but i'm seeing a bit more throttle tip in fueling that i think is right, which is probably accountable to my ltrims of 5-7 need to work on the VE table/spark a little more. cant wait for Wideband hptuners so i can upgrade and use my ntk-based wideband

As an update, I stuck a new bosch 13111 in the right side header this weekend. I'll continue to keep everyone updated as to my results.

I used the Vette O2's now for about 6 months. Everything was fine but I got the code again and have since found out the driver side is bad. I am going to replace both of them tomorrow again and go from there. I think part of the problem is tuning with these and not letting the car warm up right after it is started.
