Mechanic replaced a leaking coolant hose in back of engine (99 Mercury Villager) and now have check engine light immediatley. Codes are Knock Sensor and MAF Sensor. He says the Knock Sensor is plugged in and he says he checked wiring harness and everything is ok, however obviously not. The van was running ok before and now it idles a little rough at a stop. He has cleared the code and disconnected the battery twice and the light comes back on immediately.
Side note: He says he had to take upper intake off to get to the hose. What are the code numbers?
I feel sorry for the mechanic. Those engines are a pain to work on.Car Repair Talk's forum.
