I have a problem with my Cadillac Seville 1990 4.5l...
When I'm slowing down, the idling engine goes variably between 650rpm and 1450rpm and then stops.
The board computer showed up the ED31 code, but now it's the ED32 one. Could it be the MAP sensor?
What do you think?
[EDIT] Now, only the ED41 code shows up. Apparently it is linked to the cam signal sensor...where it is located? Could it be the cause of the bad slowing down?
