new intake and a little work I did last night (pic heavy)

It doesnt feel like high gear

When I'm in 1st driving around the farm and I use my breaks it will try to shut off and the lights will dim

I was told by a buddy that it might be a idle sensor but I wanna be sure before I buy one

I also have a bearing in my alternator going out but its not sqealing or vibrating

 

Painted maf sensor now just to get blue hoses and filter

 

When I add a pic it says the page you entered is invalid WTF I'll add a pic later
