2003 s2000 that wants to die when i turn my a/c on and normal when its off.

ne ideas?

 

maybe check your throttle cable?

 

i have the same porblem ever since i put in the aem ems.. its possible are cars are running too lean.. and the draw of electricity from turning the ac on is putting to much load on the engine cause the car to stall.. Do you have any parts possibly leaning out ur mix intake headers test pipe catback etc?

Also try a fuel injection cleaner.. its only like 4 bucks and could possibly solve ur problem because u might not be getting enough fuel to keep ur engine running at idle.

 

Or idle control valve can't compensate enough. Try cleaning it.
