It was the middle of the winter and I didn't have a place out of the snow to work on it. So I thought a VWoA dealer was the best thing. Man was I wrong. They wanted to put a computer in. 6 weeks later after the snow was melting I fix it by replacing a wire. I simply traced out every wire in the engine compartment from the computer to the engine. Found the temperature sensor not making a connection. Pulled on the wire right there in the engine compartment where the engine rocks and found the break. I then replaced the entire wire to the computer. I haven't has that problem since. Your symptoms sound just like mine. The only other thing I know of that will can cause these symptoms is the O2 sensor. To check this just disconnect the single wire plug. This is a good temperary check. Or a temerary fix to get you home. let us know what you find P.S. I have now found this as a regular problem in 4 Vanagons. Eric Zeno
