Codes and not all the time
I have a 2016 vw tiguan and
when I'm driving it will start
jerking and bucking real violent
then the epic light comes on and
it through a p087 code which is
low fuel pressure to the fuel rail
well this started when I hooked
up a bigger amp to my stereo
could that actually be the cause
that the amp is drawing to much
power and causing other thing
not to work properly.
