Crazy idle speed, air flow meter?

larry the lanny · Jun 7, 2010

When shes stopped revs jump up and down sometimes even cutting her out been told its the air flow meter but when i have disconnected it, while running doesnt seem to make any difference and the revs still bounce any ideas?

Well it would help if we knew what motor we're talking about.

Have you done a search?

Whoever said the problem is your air flow meter needs to think again. Idle Stabilisation Valve aka Idle Air Bypass Valve aka Stepper Motor.:search:

If it isn't that then your ecu is possibly playing up.
