The truck has had a stutter in it for a while now, mainly while towing, but it has gotten worse. I have noticed an exhaust smell getting stronger lately but there is no smoke of any kind at any time. I have replaced the FICM twice before but that was when the dealer said that was the issue. I have done the test on it and I have 48v not running and a steady 47.8v while running. I know this doesn't necessarily mean the FICM is OK and I think it is bad, but with the price of these things I thought I would ask and try to make sure before I just go buy one. I have not had a chance to buy a scanner yet so don't know if there are any codes. I replaced the alternator about 6 months ago and batteries are a few years old.I am hard on the batteries and do drain them occasionally as I work out of the truck a lot. Does this sound like the FICM is bad and if so would the repair for these things be a good option or should I just break down and buy a new one?
