Hi all! I am having a new issue whwre the car idles low and stumbles and stalls until it is warm. I have to give it throttle and keep rpms up at like 1800 untill it's warm, then it idles normally. Once warm, it drives normally, pulls normal 21inHg vaccuum, pulls great at WOT. Ambient temperatures aren't all that different from a couple weeks ago when she was working fine.

I haven't changed anything in the tune OR mechanically since before the issue began. Which leads me to believe it's a mechanical issue. Any culprits come to mind?

PS I tried to search for this but there are so many posts about idle tuning I couldn't find anything about new unique problems with an unchanged, otherwise working tune.

 

Need startup log

 

Thanks for asking, log is here.
