After thinking that I resolved the issue my CEL came on again.

It doesn't come on during driving but after it's been sitting awhile then it turns on when I turn the key and then after I start up it stays on.

Any suggestions or check list before taking it into Autozone to pull the code?

Anything I may have overlooked?

The ESM was sodered the first time so I may have to double check they were sodered right.

What about issues with the fuel pump? or FPR?

I've checked the hoses so many times, I'm pretty sure their right. There is a "check valve" on the long hose that connects to the "Y" connector. Is this a one way valve? and which way should it be facing?

Comptech SC w/AC.

Any insight would be helpful...

 

You have to get the code before chasing your tail trying to fix it.

 

Thanks guys for the response to my PM's... I feel much better knowing I have more minds helping me brainstorm...

I'll pull the code first thing and post up..

 

Pulled P0411 secondary air injection incorrect flow. Does this also apply to the aftercooler pump hoses? or just the ones for the intake?

Is it possible to screw up the 2 hoses to the front mount Aftercooler by putting the wrong hose to the pump?

I'm confused...

I'm assuming this is similar to a CAI installation with the hoses being wrong..

 

The comptech AC pump wires into the Air pump relay. you shouldn't have disturbed any of the big air hoses to the pump. Check all the vacuum lines just like a CAI install.
