Hi All, I have a 1994 Sonoma 4.3L vin w with a intermittent hesitation with moderate throttle in the 1500-2800 rpm range. Bought used with many issues and am mostly down to this hesitation and some knocks. After months of tearing my hair out (many problems, many parts), I'm reluctantly at the point of admitting that I can't seem to fix the hesitation. My current work-around is that I have found that if I force it to run in open loop all the time (by setting "Minimum Temperature for Closed Loop" to max), the hesitation is not there. What effects/problems/damage might happen with running forced open like this?
Thanks in advance.
