Lamba madness. Really bad Jerking (almost like the fuel is cutting in end out every sec at neighborhood speeds Upstream O2 replaced (single bank conversion). HPFP was replaced with an extra HPFP I had laying around (I thought was good).
Lamba jumping like crazy (I was keeping rpm around 1250) Already replaced my HPFP (with a used one I had laying around, was pretty sure it was good, maybe not..) replaced my upstream O2 (single bank conversion).
