The engine of my 1984 Toyota Carina AA60 works great when idling without the air conditioner running, but immediately after switching it on, it idles very badly, and a big noise starts up. If I move my car forward, it feels like the engine has a lot of load. Also, the A/C air speed increases with my acceleration. I am hearing a 'click click' noise right after I use the accelerator. This is a terrible feeling when I am in traffic.
We have re-installed an A/C compressor, and the A/C clutch is working very well. The A/C belt is not too tight, but I still have the same problem.
One of my friends said that there may be an issue with the gas inside the compressor. Does that sound right? What else can I look at to solve this problem?
