99 GTP Borla cat back with High flow Cat
Have you installed the O2 simulator yet? Also, do you have a check engine light?
No engine lights and it has an O2 sensor installed
sensor or simulator?
when i replaced my exhaust i re-installed the factory O2 sensor
why?
should i use a simulator instead??
do you have an aftermarket exhaust? what exactly do you have for exhaust? if you are running rich your service engine light should be on?
Yes i do it's a Borla cat back with high flow cat.
thanks
actually today i just noticed that if i punch the gas and let go my car back fires what's with that..
all high flow exhausts do that...my 2002 does it
