Engine Stalls When A/c Turned Off

[lexusted64]

Just bought a 95 SC400 with 220,ooo km. The engine will stall either right away or when I come to idle, if the a/c button or the climate control-off button is pushed while driving.

What is the problem?

I had the same problem on my 95' SC400 a few years ago....If I turned the a/c off while driving the engine would stall. After searching this forum I found that the problem was a dirty throttle body. Cleaned the throttle body and solved this problem. Do a search here...there used to be instructions on cleaning the throttle body without damaging any sensors.
