I have 13 codes that came up. A few of them are because I have ory and never had it tuned out. Also the same codes came up listed different times on the scanner. The issue I noticed with the car is a strange idle. Not huge but I know its there. I wanna hear some opinions.Heres the codes.......
p0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P0140 - 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
P0153 - Oxygen Sensor Circuit Slow Response (Bank2, Sensor1)
P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0160 - O2 Sensor Circuit No Activity Detected Bank 2 Sensor 2
p1133 - manufacurer control fuel air metering
p1153 -
p0135 -
p0140 -
p0153 -
p0160 -
p1133 -
p1153 -
Why would these same codes be listed more than once?

Iv been running the lts ory for a few months without problems untill a couple days ago.
Also idk if it can have anything to do with it but I noticed my tail light was out so I replaced the bulbs. When I took the cover off to change them the cover had lots of water in there and one of the bulbs was actualy broken. The whole bulb connection was sitting in water for a while. Kinda weird cause it happened around the same time I noticed the weird idle.

Ok I took out the front o2s and replaced them with the other 2 I had in the stock exhaust. I reset the codes. It took 30 miles and a good wot punch to set off the light again. The codes I have now are....
p0140
p0160
p1133 x 2
I know the first 2 codes are because I have no cats but the 3rd code shows up 2 times on the scanner. Whats could be throwing this code? I know its for air and fuel metering. Also I hope all the others dont come back

According to a quick google search p1133 is for Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1 (Rear Bank)

I just copy + pasted from here: http://autorepair.about.com/cs/troub.../bl_obd_11.htm Should have read it a bit I guess. ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
They have 1134 as b1s1 (rear bank) as well, but 1153 and 1154 as b2s1 (front bank).
I wonder if maybe they're refering to a transversally mounted engine with the front of the motor on the passenger side, then refering to the O2's for 1,3,5,7 as front bank and the O2's fron 2,4,6,8 as rear bank?

alright,although Iv never had a ls1 with a completely smooth idle I think the extra rough idle is gone. At least for now anyway. It was the front o2s.
Now I just have the other codes because I have no cats. The p1133 - manufacurer control fuel air metering I have no clue about.
