The van has been running very well the last few months after all that tinkering.  City gas mileage is still not where I’d like it but I ‘m going to check the highway mileage next week.  Anyway, I have this persistent problem.  If I accelerate to really high RPMS, like in 2nd gear, I get to a point where the engine just cuts out like a switch.  This is 100% reproducible as it does it all the time and the engine runs fine otherwise.   I don’t have a tach so I could not tell you how high the RPMs are. I do have a big clock so I could tell you what time it was, except in the winter. 

Any suggestions?  I have an ‘83.5 WC.

Thanks,
Bryan
