Engine light just turned on
 

Hi guys, just had a afterburner vortex cat back installed and my engine managment light has just come on. Any ideas what it is and what I should do?

More info. What car is it,mods ect ect

It's just a standard 04 impreza sti. But now has the cat back

Internet diagnosis ftw!

Seriously get it plugged in, most likely needing a map to suit to the reduced back pressure with the exhaust or could be something like a split hose.

Can buy the dongles to read yourself from the likes of amazon to use with android phones or iPhones.

This is a silly question but would you still say it's safe to drive the car even with the light on? I'm guessing it's a sensor

+1 what he says
If you need to use it the use it off boost until you know the fault and get it mapped to your new higher flowing zorst

Strange regarding just having a cat back... I have fitted the same to my 53 plate WRX and have had no issues :wonder:

For the peanuts they cost I cannot recommend one of these enough...


I bought one thinking it was going to be a heap of turd but surprisingly has been helpful on various vehicles including my scoob, allows diagnosis of codes and resets them ;)

Just put a bottle of cataclean in it and a few miles later it's gone :) cheers for the help guys
