Stalling when A/C turned on
I have a 1987 ford f150 4.9L straight 6. My truck
idles fine when the a/c is off but as soon as I push
the button to turn on the a/c it dies only at idle.
When I go down the street or high way it works
great. But when I stop it does. I have cleaned the
idle air control valve and throttle body and the
truck runs better but has the same issue with the
a/c. I've been researching this issue and still
haven't found anything on this. Does anyone have
any idea whats going on here?
