2005 S40 T5 Rough Start in heat

![Default](/forum/images/icons/icon1.gif)
Not sure even if temperature has alot to do with it, but seems to choke on startup (can't catch, sputters,dies). Second crank is ok, sputters some, just catches, and takes a few seconds to get to idle.
Just replaced battery. No engine light (so rule out misfires on bad spark plugs)? Could it be bad fuel sensor? Fuel pump? Air filter? (air filter not sure how old, 1 year? 3 years max?). Have been using Regular gas for about 9 months, used to put in Plus all the time.
Rough starts have been happening probably past 2-4 months? Seems to be getting worse, but maybe because days are hotter? Seems worse when car has been sitting in the sun for a few hours.
