@Jason_B Check your vacuum lines particularly where there are bends and it goes into the intake manifold. Any leaks seem to really affect the brake pedal feel in these trucks

 

If some of the small Secondary Air Injection lines are loose, could that cause a vacuum leak? I am also chasing a bumpy idle that comes and goes, and a check engine light if I let it idle for a really long time. To me this all seems like it could be a vacuum leak. What is the best way to test this? Smoke test?

 

Smoke test is how they do it at shops.

Yes those SAI rubber hose ends get loose and leak.

Possible source of vacuum leaks: Three hoses on passenger side of intake plenum, brake master, SAI, PCV. Plenum gasket, Fuel injector O rings...

I had same symptoms, I had both the crank case breather tube nipple loose leak and the fuel injector O ring leaks. Code P1171

 

@Jason_B Here's a link to the smoke test I rigged up which easily found a couple of my issues. https://landroverforums.com/forum/di...15/#post709433

 

Finally got my custom built rock sliders from Dark Crow Designs. Looking forward to priming, painting and mounting these this weekend!




Much like the bumpers, this is really stout steel.

Finally got these primed, installed and painted. One coat of herculiner today - I will add another coat tomorrow.

Etch and prime

Very Nice

 

Thanks Richard. The guy from Dark Crow Designs does some really nice work at a price that is comparable to the ARB stuff. It's all unfinished steel but its pretty easy to finish it up with whatever coating you prefer.

 

Looks great!

 

Hi, They don't offer powder coating? Do you have a link to this Shop?
