I have had this service light for a few months and I have been doing a lot of others thing lately around my house and have no had the time due to work and renovations. Is there anyway to fix this problem on my own I know that it deals with the IMRC valve being stuck open bank 1? People have said the brackets holding the arms that open the valve might be broken but I have checked and they seem good and tight so I am assuming it might be the actual runner control? Anyway to fix it on my own?
