Okay I think i have found the problem, but not positive. . .

I looked up where the Secondary Air Pump/Secondary Air Injection System was and the pump and unit look to be in fine condition but its missing a "corner" piece of a hose COMPLETELY!?

Could this be causing my idle problem, and if so how do i know what part number this hose is since it is completely missing??

 

I can't wait to yank that ugly piece of garbage out of my engine bay.

 

It won't affect idle quality. Thats not your problem

 

Yeah... you had that code that said you were running lean, right?
Could very well be a MAF causing your rough idle. Post up all your codes again.

And yeah, the SAP shouldn't do anything other than make a crazy noise and throw a CEL. Yank it!
