My SES light came on yesterday so i took the car in they pulled the code then wiped it so the SES light went off and told me it was because of my cutout is this comman or do u think there is somthing else wroung with the car and they just can't find it

 

DO YOU HAVE ANY OTHER PERFORMANCE MODIFICATIONS DONE TO YOUR VEHICLE?

I HAVE A CUTOUT, AND I AM THROWING A SES CODE, BUT IT ISNT BECAUSE OF THE CUTOUT. IT IS BECAUSE MY CAR IS RUNNING TOO LEAN.

 

nope just the cutout the guy said something about a sensor and that he checked it over really good and that the cutout was the problem i run my cutout open 24/7 so i don't know

 

HMM, THE SENSOR HE MIGHT BE TALKING ABOUT, WOULD BE THE 02 SENSOR.

BUT I DON'T SEE HOW A CUTOUT WOULD MESS THAT UP, WHERE IS YOUR CUTOUT LOCATED?

 

right under the front passenger seat the car also has some what of an incosistant idle but is fine under accelleration the SES came on to day on the way back from my girlfriends it comes on and goes off pretty frequently now i wish i could solve this problem so i know if i need to spend the money getting it fixed or buying mods

thanks by the way

 

The only way to properly answer your question is to know what code the computer is throwing. That's why the light comes on. The computer wants to give you a message... "The [xxxxx] sensor supplied me with a reading that was out of the normal operational perameters." From there you can diagnose what to check. Otherwise you just have to take your mechanic's word for it. It could be anything.

 

he told me he went over every thing and nothing was wroung and the code it pulled was the sensor it was a trusted guy did it free anything else it could be do other Z's have a incosistant idle like mine

 

But which sensor? O2, Knock, MAF, ...

 

dam theres more then one well don't know moms pathfinder has had the SES light on from the O2 sensor for a year now there like 80 bucks for her car and it runs fine is this somthing i should really get checked into and worried about or should i continue modding got cash burning a whole in my pocket but i hate that dam light i hate with a passion

by the way thanks a lot this is the best place to come for advice i feel like i'm surounded by mechanics

 

Check your air hose leading to your O2 sensor. I had to move it one time which made a kink in the hose where I couldnt see it. Fried the O2 sensor.

 

If your cutout is located after your cat, then it's not the cutout causing the code. Only way a cutout would cause a code is if you put it before your cat, which would mess up the readings in the pre-cat sensor. Seeing as you have an LS1 though with dual cats I'm assuming it's after the y-pipe so the cutout isn't the problem, I don't care what the guy says.

Chances are it's an O2 sensor or something, you just need some more specific readings.

 

so what do yall think should i not worry about it and keep modding my car and just it with the SES light on or go some where else for more dionostics and spend cash on that

 

next time the light comes on, find a local board member who can pull the code. Or just take it back to the same guy and ask him for specifics. I wouldn't mod a car that wasn't 100%. But that's me.

 

Might want to have AutoZone read your code and post the code here if you want more info.

I've never heard anybody throwing a SES just because of a cutout...

Like 2002Z28SSConv said, it would be a good idea to take care of the reason for the code before modding your car more, though.

Good luck!

well i took the car to autozone and they pulled the code and said that my car was running really lean and suggest i buy some b-16(i think it was) to try and clean the fuel injectors i've driven like 15 miles whit it in the tank and the SES light went of once but came back on any other suggestions on what it could be and how to fix it
