2012 acura 3.5 cold start hesitation and stumble
Hi, Guys
Had my Tl starting perfectly in the cold morning even in NH coldest morning. There days which are warm. Noticed some hesitation and Stumble at first start after overnight or two days not driving. I do not if it is hesitating. But it sounds not at right rhythm as before. for instance, normally, 3 times cranking then start right away. now it cranks 3 times but starts a little bit ahead or deferred. it is hard to explain. it starts not smooth or fluent since these days.
2012 fwd TL, 29000 miles on it.
Any ideas?
Thanks

You could have some phase separation of the ethanol from the gasoline. It's a know problem by the US Gov but they mandated the use of ethanol anyway. Ethanol also retains water which also could be separating out in the cold temps. Try some pure gas if it's available. Ethanol-free gas stations in the U.S. and Canada I'm not saying this IS your issue but it could.
