I went to a buddy's house last night, and was parked nose- in on a little bit of an incline. When I wet to leave, the car started sputtering something fierce. I pulled into a parking lot, and pulled the codes, and had a p0301 & p0201. Limped it home, cleared the codes, went in to bed. Got up this am to run one of the kids to school, and it drove as good as ever again. If the injector's going, NBD, but it strikes me odd that it only happened after parking like that the night before. the day prior I had driven 150-ish miles with no issues whatsoever. I know that at least my sending unit is going out, but fuel pressure was around 53 psi at idle, so it seems like the pump and FPR are otherwise functional. Maybe crap in the tank? That seems a little strange too, as it's always fed top-tier 93 octane. Any ideas?
