Okay guys here is a new trouble:
I am running my Viper on VEC2 and 6.5lb pulley.
In hot weather, I remove plenty of fuel using the fuel trim feature in the VEC2.
Over this week-end the temperature suddenly dropped from 60F to 30F.
I was unable to easily start my Viper. The start was looking like starting a WWII airplane. I had to start the engin something like 3-5 times and the engin stopped always. Finally I got the message and instead of removing fuel I just added a couple of ms of fuel to each cylinder. Now the engin starts perfectly.
In fact during my trouble the engin was idling around 24 AFR !!!
The PCM should add fuel when temperature drops.
I have the impression that PCM doesn't do it.
What's going on here ?
Anybody with similar experience in cold weather ?
