01 excursion throwing some codes
The ses light has come one. I had a guy check the codes last week, one was P0720 for speed sensor, the other 3 I can't find the paper that I had written them on but were, intake heater, glow plug cylinder 1 and another speed sensor one. He cleared them but then the ses came back on. I just had him check it agian and the same codes came up but the p0720 was pending (I think). I should of wrote them down agian but I thought I had the paper from the first time. It also is cranking over slow to begin with. I have removed the intake air heater and plugged it off. This problem started when all I did was start it up move it to the other side of my truck, rotated the tires and then started it agian and that is when it through the ses light the first time. any help appreciated.

Time to ohm the glow plugs. The excursion has a GPCM so it will throw a code and trip the SES if a glow plug goes bad. Double check the code, but if it's cylinder 1 throwing the code, ohm the wire. Sounds like you might be replacing a glow plug soon (don't use autolite).
