Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,Since the garage the did the fist repair has not been able to find the source of the problem I would consider finding a new garage and getting a second opinion starting with having them run a scan on the computer system to see if there are any fault codes setting which there should be since you have had this problem return several times. I suspect the problem may be related to the first repair you had done but you need a fresh set of eyes to have a look and at least tun the scan for you. Once the system is scanned and the fault code retrieved it should be fairly easy to determine the cause.
