A while back I posted about the F250 I bought for my son. It was running extremely rich (blowing black smoke, carboned up spark plugs) but the engine codes were showing that it was running lean. I couldn't figure it out and I brought it to one shop that I had been having pretty good luck with. They replaced the O2 sensor but it was still running the exact same way - they claimed they looked for vacuum leaks and couldn't find any - I couldn't either. Their opinion was it needed the cats put back on the truck to make it run right. I knew that wasn't it because the sensors on this truck were all upstream from the cats - no sensors after the exhaust went through the cats.
Brought it to another shop where the guy "specialized" on Fords. He found 3 vacuum leaks - one of them being a huge leak that powered the climate control (reason for the lean codes). Then he found the fuel regulator was leaking a lot of fuel into the vacuum system (reason why it was running rich). The owner previous told me the truck had running issues when I bought it but he couldn't figure it out. I had replaced the IAC and that had made it run and start a lot better hadn't figure out why the code conflicted with how it actually ran. MPG went from 4 to 14 (5.8 w/auto) before and after his repair. His price was $215 to actually fix the truck as apposed to "working" on the truck.

In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together.
