well i replaced the input and output speed sensors on my 2001 xg300. when i tried turning it on it turned on and stayed on. i then realized the AC was on. i turned it off and to my surprise the engine cut off. i tried turning the car back on but it the engine would shut off within a few seconds of sgtaarting up. i turned on the AC and then after struggling a bit the engine stayed on. but as soon as i turn off the ac the engine cuts off. if anyone can help me please let me know because the AC in my car doesnt even work and i dont want to drive around with hot air blowing in all the time. its summer and i live in california this would b unbarable. thanks in advance for the help.
