Looks like you've got your work cut out for you!

Create a build thread for your truck or do a thread for each one, your preference.

When you start tackling these, make note of the 2 digit symptom code after each trouble code and look to see whether the code is current or historical.

Then, when you delve into the shop manual for a particular code, they will often list right away all the codes to solve first before yours.

Thank you, I will do so. I'll probably post it tomorrow. I do have the 2 digit codes I believe as well, didn't know what they meant though.
is there a online resource for the shop manual?
