check engine light
 

hey guys

I just had my exhaust done on friday, ooo ya shes loud now. And now the check engine light is on, is it possible that because of the decrease of back pressure that there is more fuel being injected and the o2 is picking it up.

Thanks

hook it up to a code scanner and avoid the guess work

since you said code came on after exhaust replacement i would check your o2 sensor to begin with

^yup.

Jump the service connector and read the code. If you dont know how to jump the service connector, search it.

i bet your o2 didnt get plugged back in right :P

probably^

thanks 4 the suggestions guys. I think i will try a code reader. And the o2 wasnt touched, i only had the cat to the muff replaced soo.
