Just put some Ebay 4-2-1 headers on my friends 00' GSR. Got a CEL. Im assuming its due to the O2 getting a lot of air. Can someone correct me and give me a hint of how to fix it?

Thanks.

 

well.... i had ebay header and it didnt throw me anything ... try to get a different o2 sensor

 

Did you reset your ECU? Just pull the plug and ... wait... then plug it back. Worth a try.

 

replacing a header and the fact that its ebay has NOTHING to do with a CEL light. check the codes and see what the reason for the CEL light is and then address the problem...

 

I just figured putting a better flowing header that throws more air would confuse the sensor. No?

thats what ive been told about my 99 LS after the header install, they said something about OBD2, but i forget exactly what was said...

 

Yeah idk man. Anybody know?

 

Nothing no one can do until you pull the code and tell us what its saying..

 

Im going to get my hands on one tomorrow.

Until then.
Thanks

Yea I will look into it tomorrow morning. Thanks for all the help guys.

 

was it on an obd1 or obd2 car?

just check the code and see what it is...

 

Make sure the o2 is plug is on all the way. Had this happen to my roomate just the other day. But obviously just run the code first.

 

Which "brand" did you buy? I know some of them will not pass emissions but it has nothing to do with the CEL. Do what these guys said, make sure the 02 tight all the away...
