Years ago I had a fox body 5.0 that idled bad and was running rich. After I found a scanner that read obd1 it gave me codes that lead me to replace the coolant temp sensor and a air temp sensor. after I replaced them the car ran like a new car. I see the 1996 cobra has a coolant temp sensor and did not see any thing for the air sensor. Will the coolant sensor fail and make the idle low after cool start?
