2004 Disco 2 Engine Rebuild
#222
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
