[DML] High Idle, Chapter 99

[Woody <BePositive2000@xxxxxxxxx>]

I tried my other ECU and Idle speed computers w/o change, but did find
out something else when I checked fuel system pressures.  The pressures
were within tolerances for normal engine thru warm-up, but for some
reason, the idle went up as the system pressure went up thru warm-up
(starting at 900 rpm, ending at 2600 rpm).  Since warm engine idle is
high even with the CIS disconnected, and since the idle cannot be
manually adjusted to a low idle, I'm beginning to suspect that the
control pressure reg might be the problem.

Follwing warm-up, my dwell gauge also showed a wide swing in dwell
(bouncing from 20% to 50%) which I believe would indicate a rich
running condition.

Thanks once again for the input and any further suggestions would be
appreciated.

Woody
