Hi,
Are there no vacuum hoses whatsoever? I'm surprised it was running. LOL Regardless, I attached vacuum schematics for the EVAP system and the 4wd system. For some reason, the 4wd schematic is somewhat vague.
Take a look through them and let me know if you have questions. I'll try my best to help from here.
I hope this helps.
Take care,
Joe
