I’ve been daily driving my 83 K5 for the most part but I’ve got three reoccurring codes, P006F(Boost Control), P1800(ECM to TCM Engine Coolant Signal), and P0006(Fuel Shutoff Valve). I’ve tried googling it and I can’t figure anything out. I can clear the CEL and drive the whole way to work without it coming on, but it’s on when I start it to leave. The only side effect I think I notice is the way the trans shifts, it seems to hold gear longer and not shift to overdrive with the CEL on? Other than these codes and the steering wander I can’t figure out, so far it’s been a blast to daily drive.
