Would like to help a fellow out that I work with out to the extent that I can.  Here's the deal.  The car is a 1986 Lotus Esprit turbo, having Bosch K jet tronic fuel injection (I assume it to be like a VW and/or Audi, there's the Audi content).  The car exhibits two symptoms:

1.) While running at idle there is the click...click...click.... sounding like a relay toggling.

2.) When coming totally off the gas there is a tendenacy to backfire like.  There is this economy mode, that apparently Lotus added, that is supposed to cut off all fuel delivery when one comes completely off the throttle at speed.  Does seem to be doing that, hence the backfire like condition.

3.) The guy would really like a book or service manual for this Bosch system, aka the "Bible" showing and describing all pins outs associated with the ecu.  Seem to remember someone mentioning that sort of thing here for a Bosch system.

TIA,
