I've had this problem for awhile now, but tonight it was bad enough to piss me off. It actually has't done this in awhile, but I figured I would ask the peanut gallery.
When I fill the car up, or really anytime I buy more than about eight gallons, it wants to spit and sputter and miss something awful. Usually if it dies, when I get it started, the exhaust is rich something awful.
Tonight, I filled up 11.7 gallons in a 12 gallon tank. I went to go leave the parking lot, and it dies by the road. This isn't out of the ordinary, and didn't think anything of it. I pull into the drive-thru and once I stop, the car dies. I restart, play with the throttle enough to get it at idle. Normally this is where everything is fine.
However, once I touched the gas to pull ahead, the car dies. Repeat this five or six times until I leave the restaurant. Take food back to said gas station (wife works there). I leave the car running, get back in and everything is peachy.
Now, the OBDII has said before something about a knock sensor, which I know is halfway common on Nissan products. However I'm not switching octane ratings, so I don't see how that's effected. It also mentioned something of the evap system, I just can't remember what code, I need to rescan it.
For reference sake, its a 2001 Nissan Sentra, 2.0 manual.
