As soon as I started the re-charging process, the car stalled. It stalls every time I attach. It almost seems that it does it as soon as the clutch engages. Does this mean I have a bad clutch or compressor?

You run a real good chance of destroying the whole system. AC is not a DIY repair. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

The car is telling you that it doesn't want you do be doing that. Best advice is it to take it to a shop that specializes in AC repair. They can recover the refrigerant out of the system and tell if it is low or not. If it is low, they can recharge to the correct weight and add a dye to find small leaks. They can also monitor pressures and tell if anything is wrong that isn't refrigerant level related. The ac recharge kits you can buy at the auto part stores and Wally world are not good to use because automotive ac systems are charged by weight and not pressures. The small ac systems now a days don't take kindly to over or under charging. Some compressors use variable displacement technologies and you'll really be off if you charge by pressures. There are no top offs anymore, so take the kit back and get a refund. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Just hope it didn't wreck anything already. It may not have needed a charge at all. As HT said this is not a good DIY thing without some extensive knowledge and the equipment. For now at least get the refrigerant removed, measured OUT how much was in it then find the real problem.
