I have been on the road working for the last 3 weeks and my wife has been driving my SD and I have her toyota for economy. I came hbome this weekend and had to get in the SD for some real truck driving and noticed that my tach was cutting out then back on. It falls to 0 then jumps back up at about the spped of the guage test. It seems to be a random issue. It does it when it wants to not over every bump or at a certain time. Then I noticed the speedo would jump 5 or 10 mph real fast every now and then. Then the CEL and check guage light came on and I immediatly looked at all guages and saw that the temp guage had cut off then come back on. No problems with the running of the truck or shifting. Almost like the cluster is shorthing out or the computer is freaking out. I have a little less than 171K on the truck. Any ideas?
I just did the cluster test and all guages functioned properly this time but I got several codes. If anyone can decifer these maybe it will steer me in the right direction.
D262
D027
D058
D059
9352
Also my SCT X3 is not showing any DT codes at all. Does it not read these particular codes?

I recommend the following:
1. Return your PCM to stock tune.
2. Disconnect your battery for 30 minutes.
3. Check for codes. If present, continue to research the codes and repair truck. If not present, then go to #4.
4. Re-load SCT tune.
5. Check for codes. If present, continue to research the codes and repair truck. If not present, then the problem is fixed.
