  After chasing, for over a year, a stumble that occurs as boost goes over 
5 lbs I had the remarkable encounter with a person who knew exactly what 
caused the problem.  Strange, how solutions to problems present themselves!
  Anyway, he told me that the Nissan 280's have a problem with the ECM, or 
ECCS, connectors.  For some reason they become corroded and for some reason 
this causes a stumble.  He said that they, in his shop, pull the connectors 
and spray them with WD40.  Well, gasp!  Not trusting WD40 to the task I 
used CRC contact cleaner, worked the connectors in and out, and low and 
behold, the stumble disappeared!!!! (:>  ZM000000M
  Now, what can I do to solve this problem???  Is there some chemical that 
I can use that will stop the corrosion?  I thought about removing the 
connectors and using connectors like on my computer, that could be locked 
into place by set screws.  This is a lot of work.  Surely there must be 
something that can be sprayed, that will do the job!
