Diagnose my truck

Sounds like a vacuum leak to me.

 

Maybe I'll tape over all the ends to see if it helps before I buy all new hoses. I need to find a diagram with all of them to find out what all I need in what sizes

 

If you have known vacuum leaks start fixing those and what code pops up?

 

Have one of those big Bernzomatic torches? Open it up without lighting it and press the nozzle along the vacuum lines and under the manifold, listen for a change in engine sound or better yet, look at your scanner for the o2 to go rich.

 

Only code that will pop up is too lean on bank 1 and it isn't on right now

 

I'll try that over the weekend or after Christmas, I haven't had time to work on it much in the last week. I'm leaning toward injectors since it will sometimes get the too lean code but it needs lines anyway.

 

These are the cracks that I've found. Any look problematic?
