Yes, stock intake and BPV. The car hasn't been driven in rain a long time, in fact, another relevant point, is that I recently started driving this car again after almost two years, although I had been driving it again for about a couple weeks before it started acting up with no issues. I suppose at this point, I'll replace the plugs, and pull the injectors to have them tested. At that point if I'm still having issues, I'll swap out my maf with a buddy. I'll keep you guys posted.

BNR 16g turbo, downpipe, ebcs, fuel pump, and protuned. These have been the mods for some time now.

On my way home on the highway, my car suddenly started running rich. My af correction stayed around -15% keeping my afrs at 14.5, but as soon as I went into open loop and I lost my af correction, it would go pig rich rich immediately around 10-11. The car drove fine as long as the af correction kept up. I stayed out of open loop and got back into my town about 20 minutes later. By the time I got off the highway, my af correction would be at around -18% and bottoming out at -25% as I hit lights, until eventually a hill killed me since I couldn't stay out of open loop. I rolled the car into a parking, and couldn't see anything upon examination. Car wouldn't start at this point, it would just turn over and act like there was way too much fuel being dumped in. I about gave up and was going to start walking home when I gave her one last try, and sure enough, it started up perfectly fine. During the quick 5 minute drive home, my af correction hovered at 0% and the car drove like nothing happened. But then I tried taking the car somewhere the next morning, and as the car was warming up about a block away, my af correction started decreasing down to 18%, which is when I turned around and took my other car. I tried to start it just now, and it started but it sounds like I fouled a plug and it's running on three cylinders. A ton of smoke came out the exhaust from the fuel. I'll replace the plugs, but I don't know what to do about the rich condition. It seems very odd. Electronic related? MAF? Fuel pressure or an injector? I don't really understand how any of those would allow the car to start right back up, drive home, and then right back the next morning.
