Michigan Help - 1999 F350 Hard Lumpy Starting
I bought a '99 F350 with 178k, 6 Spd Manual, work truck with a flatbed. The guy I bought it from had it nice and warm when I test drove it. The next morning I found truck misses quite badly and doesn't want to rev - super lumpy and low power until it warms up. I started plugging it in and it starts a lot better and levels out a lot sooner. Once warm the truck pulls hard, has normal boost patterns (I added a gauge) and idles perfect. It runs rough for a good few miles down the road when plugged in and longer when not plugged in.
I did check the glow plug relay and it looks to be working correctly. I am located in South Lyon MI and am looking for someone that can troubleshoot the problem that knows these trucks.
