Had a blinking check engine light. Book said the cause was a misfire. Thought I could have bad plugs and/or wires. Also maybe a bad o2 sensor. Took to autozone but they could find no code errors when they ran a diagonstic check. I did unhook the battery, would that clear the error codes? Any other way to check which o2 sensor is bad?
Bad o2 sensor ford windstar?
