Subaru forester turned on the air conditioner, got off and started slowly.

Clean the throttle and air intake, and check the spark plug gap. Subaru Foreman's engine has too much carbon deposit, or the spark plug gap is too large, so it is difficult to control the system when turning on the air conditioner, which will lead to frustration in starting. Go to the repair shop to clean the throttle and the carbon deposit at the air inlet, and then check the spark plug gap. If the gap is too large, replace it with a new spark plug.
