Any one have an info on a CCC code 41, no ref signal?.
I'm confused, runs great but SES light, and code 41.  
This is about a 1228079 MY 87 CCC (ecm carb)

I found a reference to code 41 on CCC. It says vacuum
applied to MAP with key on and engine not running will
set a false code 41. This is on 87 Olds CCC.

Maybe a bad MAP. It says to check voltage on MAP
and watch as hose is disconnected.
