high idle
#11
I've seen this type of issue once before on another forum where codes where many and high idle. Ended up being the ecm and it was due to board trace corrosion. Your codes are not the usual plain vanilla types which makes me think something is really amiss with the ecm. Did you do anything with the molex connector to the ecm?

by molex connector do you mean the harness plug for ecm? if so I dielectric greased it when computer was out
if I can get an ecm used do I need the alarm ecu also ? does it have to be from a 1998 disco?
if I remember trace means the board has gone bad not the components on the beard and is non fixable correct?
when I left the dealer idle was 1300 then drove 40 minutes to dads shut off, at resart( still warm) 900 then slowly climbed back to 13/1400

Yeah, I thought you mentioned dielectric in a previous post.
It's not a bad idea to grab the alarm just in case. Some have had no issue with their alarm working (Higgs Boson and Savannah) with a new ecm. I grabbed mine from Paul Grant who only sells them paired.
Since you have AEL you'll need 97 1/2 - 99 1/2. I would grab the latest possible since it will have newer firmware which can make a difference in engine tune. LR modified the code as the line matured.
Traces are fixable with the pro equipment and the patience of a saint. I'd go the newest ecm route if I was you.

Haven't heard of a RR GEMS swap and I doubt they would cross over simply because of the body control unit. Alarm is a plastic green box near the ABS ecu which is silver, passenger side under glovebox nearer to kick panel. Can't miss it.
Not worth sending out, keep it cheap. See if you can nab a couple of units.
