2014 with near engine stall upon startup...

OK. Will investigate that to make sure. I'm thinking that's not the issue, but worth the look. Thanks.

Went to a Shell and have used over a tank of 87 octane Shell now. So had the issue with Costco and Chevron 87 octane. However, with Shell, I only had one start up so far that had the near stall and it wasn't as bad as with the other fuels.

Thoughts?

Back now to using a tank of Costco gas and the issue returned almost immediately. Am using a bottle of Chevron Techron (https://www.amazon.com/Chevron-65740-Techron-Concentrate-Cleaner/dp/B00092893E) with a partial tank of Costco gas starting today and see if that makes a difference.
