Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
If the wrench light came on it means there is going to be a code stored, we need the code to diagnose this. You could get a free scan at any auto parts store. Let me know what you come up with.
You could have a misfire causing the lack of power/ jump. This could be caused by a lot of different things, coil pack, vacuum leak, sensor problem. The first step is to get the codes.
