MC ISV Controller-Installation Ideas??

[Ero Rademer]

Hi!

I had been very deep inside my ISV controller module while digging
for an apparent bad starting condition. The engine was a KP engine
(CIS) with a 393L ISV controller (5sp manual). The car had the
same symptoms you describe (4k, drop to 3k, stay there then slowly
drop to idle. In my case I stumbled across the circuit for the
decel shutoff valve which was shot. Repaired it and the engine
behaved as it should -- after one year of ownership.

So I assume, you additionally have to hook up the decel valve to
the ISV.

HTH
So long!
Ero.
