We have 2 Ford E450s with 6.0L Powerstroke. The 2006 is the biggest problem, but they're both headaches. These are 22 passenger luxury minibuses, so they were expensive, (over $100,000 each) and we need to get life out of them. Obviously, the routine maintenance is not enough, they are constantly broken, and needing ficm and injector replacements. Any suggestions of extra preventative maintenance, mods, gauges to add, etc. to get more life out of these and keep them running. FYI: they do idle and perform tours at low speed, which obviously doesn't help, but cannot be avoided. Please help!!!

 

idle adjuster will fix your problem with idling. and by the way, post it in the 6.0 thread. you will get more responses there
