replace the clutch and coil on the compressor. Also make sure you have enough refregeriant oil in the compressor. I think its like 2oz. All honda compressors come with oil already in them if you where to buy new. But for 50 bucks for a another compessor thats not bad at all. You would probably spend around 160 or more to replace the coil and clucth on yours. Thats if this is all ac related like it sounds like? You say only when you turn on ac does your car stall or nearly stall out?
