Re: Scanningr for codes
If the O-ring is leaking.....There really isn't a way to block it with the quick release mechanism & all.
Though your booster may be leaking.....Clamp/pinch the booster line to confirm.
Can you watch live Fuel Trim Data?? A vacuum leak will show as high trim corrections at idle & correct under acceleration.
Normal trims at idle & positive corrections under acceleration would be a fueling issue. (MAF, Injectors, Fuel Pressure)
