Well, that may help narrow down where the problem is, depending on how much stuff you touched and moved.

I think when i disconnected the battery it reset the ecu the truck also sounds a bit like a diesel when smashing the accelerator and idles rough but it has done that since i got it.

Based on the year in your profile, I'm assuming you have a 4.0 SOHC. I would look at your timing chain tensioners. You don't want to be letting that noise issue go. If the chain guides break, you are looking at a pretty big repair. It might also be partially related to your idle issue.
