I first noticed how hot the '97 MP PCM 5.2L auto. CA version gets
when I was at C@C after one run at South Mountain when I replaced
it with the '96 MP PCM. The '96 gets warm but nothing like the
'97 (casing too hot to hold). The '97 PCM has not shown any symptoms
(so far) like you've experienced but I thought I should pass this
along to you.
I'm going to put some insulation material around it ... maybe run
a hose from the passenger fender opening to it to see if the heat
is from engine bay or the computer itself.
