My car is starting to stall, so I am having to run the AC to prevent this. My gas line is cracked somewhere and it is spilling gas. In addition, my car's transmission is acting weird.
The only thing to say here is to suggest you get the fuel leak fixed before you do anything. No other problems can be looked at till the fuel leak is identified and fixed. I would recommend having a mechanic, like the certified ones at YourMechanic, come and check it out for you to see what is leaking.
