Hey Gang! Rookie here with an 87 Gt 5spd 3800sc. long story short, no DTCs in January. 1st time out in the heat and she's lazy. Died a few times ( always thought the idle was too low). And my understanding is this thing was never tuned. 80k on swap. it does have a 3.4 pully, 180 t-stat and that's all im aware of. anyway, got these codes today. Some of these I've never seen before so before i head down the google hole, I figure I'd see if anyone here is familiar with any of these.??
