My car keeps throwing this code my setup is as follows
05 WRX
APS 3' TBE w/hi flow cat
VF34
Pinks
Fuel Pump
Cobb AP

I have had this setup for a few months now and my car has been throwing this code for at least a month or so. I have already replaced the fuel tank gasket cause I would see fuel coming out of the top of the tank when I took the trunk apart. I figured this would solve the problem, but the CEL still came back. What other things should I have checked/replaced or what else can I do?

Is taking it back to the dealer to find the problem even an option considering the aftermarket parts that are installed? Mind you this is not a very mod friendly dealer.

All help would be appreciated!
Thanks,
Chip

 

I'd reseat the gasket again.
