After seeing the inside of my head, it seems that I have a lean condition. What causes the Lean condition and how can I fix it?

There is a mixture adjustment screw on the air flow meter. It works by opening or closing a bypass so more or less air flows past the flap in the air flow meter. It's enfluence is primarly at idle and low speed.
Before you pop the top off your air flow meter and start adjusting the wiper and/or spring make sure you don't have vacuum leaks and the engine is tuned properly (pts, plugs, valve adjustment, etc...). It took me seveal days working on it to get the air flow meter adjusted back close to stock after someone had "fixed" on my VW bus. Jim |
