getting a 506 fault code ( idle too low ), when running my AC, someone suggested replace the IAT.If I run without the AC on the code does not come up. it seems when i'm on the highway everything is fine , when i'm in heavy traffic the air gets warmer, i can feel the engine stutter, the code comes up and it begins to blow warm air. when i'm back on the highway the cold air returns. any similiar problems out there.

On your 80 ACCORD there is an idle boost diaphram on the drivers side of the carb.
