So it runs fine until it warms up. Then is starts to spit and sputter when i'm cruising at a steady speed but if im accelerating it's fine. I'm lost as to why it's doing this. I noticed it after i washed the engine bay. it's totally fine (warm or cold) when it's just idleing. my a/f (although it is just the autometer lightshow) it stays towards the lean side when i'm cruising. any ideas?
