Message: [QUOTE="skevac, post: 1451151, member: 5865"] My 2005 Excursion with 115,000 miles has recently started having issues starting especially when cold. It has the dreaded P0611 code. At this time it will still start and run. Sometimes it starts fine and sometimes it cranks for a while and then runs rough. I live in Michigan so we get some cold temps but it has been on the mild side for temperatures this winter. With that being said sometimes it has started fine at 20 degrees and started harder at 35 degrees. I had Bill at Power Hungry Performance tune the FICM in 2010. I haven't had one FICM issue until now. My batteries are 2 years old and it's parked in a 50 degree garage most of the time. My question is from people who have experience with this is should I just put in a power supply myself (roughly $170) or is it worth the extra money to send it out to FICM repair and get the lifetime upgraded unit installed in my shell (roughly $450). I don't plan on getting rid of the vehicle anytime soon. My thought is to put in the replacement power supply myself and upgrade the charging system to help prevent this problem in the future. If I go with just putting a power supply myself what brand brand is the way to go (Dorman, Alliant)? If this topic is covered somewhere already I apologize. I just don't have a lot of time to sift through all the threads to find the info. So, if I could get some feedback or if someone could include a link to the forum where this has been covered I'd appreciate it. Thanks in advance. [/QUOTE]
