I posted something about the headers i bought from modern performance...anyways we were able to install it but there's just one thing..
My engine light just keeps going on, I read that it is completley harmless but I just wanted to see if anybody out there has experienced any problems like this
and i just need an opinion on it.
thanks

 

What is the code? If you don't know how to check....ignition on, off, on, off quick and then it will flash codes usually with pxxxx (x being digits). It shouldn't throw a code from simply installing a header. Let us know what code it is.

 

When I put my header and down pipe on. My light came on. It showed the down steam 02 sensor was not reading right. So I put a 02 sensor simulator on. It took care of the problem. I think you can get one thru Howell Automotive.

 

Most likely is what ^^he^^ said. But if you tell us the codes we'll know for sure.
