Hi Markus,

        I hope the true mechanics on the list give you some things to try. 

        My limited knowledge is to start with the simplest things first.  Fuel or electrons.  So fuel, is it reaching the engine.  Is the fuel pump working harder?  Is there a way to check fuel pressure? 

Electrons, is there any loose grounds or other wires in the engine compartment? 
Is it time for a tune up?  

I know people don’t like swapping parts, but, do you. Have a known good AFM to swap in? 

Your van is a classic good karma van.  It needs attention but let you coast home into the driveway.  I don’t know any other vehicles that have so many stories like that. 

A friend drove my newly purchased 84 from Florida.  We got home and soon after the throttle cable last thread broke off while in the drive way.  Good van! 

Keep us posted on the suggestions and progress.

Most often seen at higher elevations or hot ambient temperatures, but summertime is just right.  This is a very common problem, after 40 years.  There is no cure, but is a cheap fix to replace gas tank.  You will need to do it sooner or later anyhow.  Of course at same time, replace the crossover tube, and every gasket and hose in the general vicinity.  Dennis was very instrumental on pointing out this problem area, and he was exactly correct.  Ken at VanAgain and GoWesty have some instructive videos about the whole situation.
