I have a D-180 connected to a Lycoming O-235. All cylinder CHT and EGT readings are accurate on EMS start-up (they read ambient), but #2 EGT and CHT are inaccurate immediately on engine start-up. #2 CHT reads anywhere from ambient to 100F and stays there, #2 EGT reads 700F and stays there. Other 3 cylinders are accurate. I tested both probes with a heat gun and they respond appropriately. How do I know if its a connection issue at the DSAB vs. faulty probes? Thanks.

I removed the spade connectors and soldered all 16 probe/harness connections. Are OLC-1 connectors better?
