Check Engine Light SES its an old subject i know but... I have the check engine light I have a diablo predator and yes I disabled the rear 02 sensors with the COT its set at 1200 degress so it wont be off. Now the codes are all the same p1133 and the other one p1153 i believe fuel system running too lean. Now i have disabled it multiple times but its just strange too me on what i should do. I have TSP true duals and TSP 1 7/8 headers also SLP lid so pretty much stock. Anyways the headers dont have i believe EGR so would that be the cause. Do i have to tune them out... those are the only two codes i did have those codes b4 the headers though.
I thought it was my oxygen sensor but i dont want to spend 200 dollars on something that still gonna through the cide is there anything else i can check. Sometimes though my car does not start up on the first crank or sometimes not even the 2nd gave me the same problem b4 the headers also. Changed the spark plug and the wires still the same problem help me please!!!

p1133 is insufficient switching on the bank 1 front sensor
p1153 is insufficient switching on the bank 2 front sensor
When you installed the headers, did you use harness extensions for the front O2 sensors or did you just hook the sensors up to the closest connector (which would be the rear connector.....and would set these codes)........no sweat if you did, wouldn't be the first time someone has. Previous owner of the project car in my sig did just that. See the link in my sig for pics.
If the sensors are hooked to the correct connector, you need to check the ground and the sensor fuse.

Well they are connected to the front and still with the light and i dont think my car is running lean because its waste quite a bit of gas. Well would the headers be also the problem because of it missing the EGR>>>??

Well I think i might need to change the o2 sensors and as for the ignition problem it could be my injectors or something. Anyone can help me on the subject.:?
