I have been working on this 97 kumina 3.1. looks way off to me
My spark advance is all ways at -8 to -35.
LTFT -10
The LTFT is not so much a bother just now, this timing number bothers me more.
I do keep getting a egr positon sensor error I will do a relearn process for the egr then clean if needed.
Any ideas as to what could cause the timing to do this. What range should it be in?
THANX
