Need Help, off idle stumble
I have a 2005 GTO
Procharged LS2
I have been dealing with an off idle stumble. I can watch the wideband go lean when this happens. I have been tuning ve via short term fuel trims to try and solve this problem but as you will see in my tune it is wacking out my ve in the low rpm low vacuum section. What else can be causing this stumble?
Ignore the wideband in this log as it is not hooked up
attached in my current tune and a recent log.
