I have a 2000 Seville STS. Occasionally I have a starting problem where it turns over fine,,almost starts,and then stops. I restart and it spins a bit more than usual but does fire up. Seems a bit rough for a few seconds but clears itself up. The Check Engine light usually comes on at this time as well. This happens maybe once a month now.
I've pulled the codes which are:
DIM u1016 history
TTM u1016 history
and then
CLM p1072 and 1075
I'm not sure but it seems to indicate both left and right banks running rich. Is this correct, and if so what might you suggest the next course of action might be?
Other than this recent problem the car shows no other codes and is pretty much pristine since I've had it over two years now. OK,,a dead battery,,but it was the original..big deal,,but the symptoms did seem to start around that time. Any link to that?.
Thanks for any help you might be able to offer.
