Bumping this old thread...I have an adjustable FPR, my car seems to be running rich as I can always smell fuel, seemingly unburned or not fully burned from the front and rear when at idle. It actually seems to make it's way into the cabin somehow, I actually just drive with the windows down. It's not horrible but definitely noticeable and annoying. Also, my fuel economy is not great, I'd guess I'm getting around 20MPG avge. with spirited driving.
It's a pretty much stock S13 Blacktop with FMIC, T28, Blitz BOV, short ram intake. What pressure would be suggested? The AFPR is oil filled, I have no idea what brand it is nor how to adjust it. Any help is appreciated.
