sup guys!.. i just got my car flashed @ works if feels so much better now and i put on a works resonated test pipe and today on my way to work my SERVICE ENGINE SOON LIGHT is on. any of you guys have the same problem ? what did guys do about it? did you guys bring it to the dealership? should i put my catalytic back on.. by the way i have a ix..

 

Dont u have to plug the 02 housing if u switch out ur stock pipe?!

 

Yup!..i have it on my intermediate pipe its after the catalytic. does that matter tho?

 

do a search on mechanical cel fix for your test pipe. it costs 2 dollars and takes 30 mins, no cel, no problem

 

well, you'll have to get the code pulled prolly but it should be related to the o2 sensor.
I remember on my 03 i had to make up a special piece to distance the o2 sensor from the bung and the cel's stopped popping up.

 

You said you got a resonated TEST PIPE.

Test pipes remove the cat so you should be getting a catalytic converter below threshold code

 

It is probably the fact you have no cat and are getting the cat efficiency below threshold.

Either search for and install the mechanical CEL fix or call Works and let them do it.

Also not to be ***** but... Search. Things like this are basic and have been covered in great detail at great length already.

 

The mechanical CEL fix works great. Search for it and you will have your answer.
