Jamie,

Easy test: unplug your O2 sensor and see if symptoms go away. If they do, replace your O2 sensor.

> Please be kind I am still a newbie when it comes to Vanagons. I have an 89 with a 2.1. I'l start it and it idles well. I start to drive then it bogs as the fuel has a blockage. When I turn off the vanagon it will start fine and continue on. This will happen frequently. I have changed the fuel filter and there is no change. Can any recommend what I should try next?
