Hey all was wondering if anyone knows what an idle vacuum reading should be on a 97 mark viii Lsc with no mods.

Just got my Bluetooth obd2 scanner and noticed the vacuum at idle is 26 to 27 psi and I also saw the Evap system hasn't completed it's obd2 tests.

Thinking there's a leak in Evap system somewhere or bad Evap controller.

Thanks for any and all help as always

Cheers
J
