i have an 06 lincoln zephyr, with 49,671kms on it. It's the v6 3.0l, automatic, i been having this problem were sometimes the car stalls out and/or has hard shifts and the wrench light comes on but then the next day, when i start it everything is fine, and no light. it seems the car does this 1 or 2 times every week, i can't take it to the dealership, because the problem never sticks around. Any help would be greatly appreciated!!!!!!!!!
