Z3 idle

[M Dean]

Do you know what would cause a 2.5 Z3 idol to occasionally fall too low and stall?

Vacuum leak is my first guess, do you have a fault code scanner ?

 

[M Dean]

Yes

Did you get any fault codes from it ?, Particularly those associated with fuel trims ...erratic idle, was a vac leak in mine, twice..
