So I did the following things:
1. Removed the evap valve from it's place and plugged both ends from the hose that goes into the intake manifold - No effect on idle
2. Tried blowing through the evap valve - No leaks so i guess that's working ok (or atleast not leaking)
3. Tried to use start pilot to look for the leaks near the throttle body - Couldn't find any leaks
Should I use a smoke machine now? What's the best place to put smoke into the engine to look for leaks (Throttle body, oil filler tube)?
What other things should i check? What are the symptoms for bad aos?
