Well I have a 93 240sx with a ls1/t56 swapped. Just finished the swap today. Full sikky kit with wiring specialties harness, also has a torquer v2 cam. I got the whole setup out of a wrecked 240. But the check engine light is on. Sometimes it idles fine, other times it is at 2k rpms. Runs rich, burns your eyes if you stand behind it. Also pops on decel, and I think it should have more power. So I ran down street and had autozone pull codes. I'm getting p0103, p0108, and p0327. Checked all my wiring connections and it appears to be good also. Where should I start?
