KHLow2008 tks for your response! MIL is functioning. Ran diagnostic and failure shown in coolant sensor. Car started when aircon was switched on. Idle not holding

Since a fault was detected with the coolant sensor, was it checked or replaced? This sensor can cause the problems indicated as the engine could be running rich or lean.
