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

 

[ExMX5owner]

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

 

[M Dean]

Ok thanks.

 

[ExMX5owner]

Ok thanks.

Its the first place to start, before delving into more costly possible causes, let us know how you get on...
