Re: [DML] Warm-up circuit

["DMC Joe" <dmcjoe@xxxx>]

Unfortunately there is no simple explanation for this behavior which is
normal to the Bosch K-Jetronic C.I.S. fuel injection system and Lambda
emissions system. If you would like to know the details of what causes this
behavior go to the DeLorean workshop manual and read D:04:08 through
D:04:10.

Note the "action circle" chart at D:04:10, the idle speed circuit interacts
with this cycling action which causes the idle regulator to vary or cycle
during
warm-up.

Keep in mind that this fuel injection system which was originally designed
in the mid 70's and was one of the first fuel systems to use electronics for
engine control. In later versions (KE, L, and LH) of the Bosch fuel systems
more sophisticated electronics help to maintain a more constant idle during
warm-up.
