loyale1993 Posted March 20, 2016 Share Posted March 20, 2016 That's about as good as I can explain it. When engine is cold I will take off and there is a short moment of hesitation and sputtering. Once I get past the hesitation everything runs fine. There has not been a cel so I'm sure there is not a code. Possible vacuum leak? Any suggestions?

It's been happening after multiple fill ups. I tend to get my fuel from the same place in all of my vehicles and none of them are experiencing this issue.

MR_Loyale Posted March 21, 2016 Share Posted March 21, 2016 I have experienced a similar thing but not on regular occasion. The one common thing are cold damp mornings. Only happens about one a month when trying to accelerate at the bottom of my hill. Feather the pedal and it starts running normally. Quote Link to comment Share on other sites More sharing options...

Feather the pedal and it starts running normally.For me it seems to happen more and more consistently every morning or every afternoon after work when the car has been sitting 8 hrs or more. However this morning I didn't notice it lol Quote Link to comment Share on other sites More sharing options...
MR_Loyale Posted March 21, 2016 Share Posted March 21, 2016 (edited) I go down a hill then turn up a hill and that is the point where it starts hesitating. I may see if there is debris in the tank. Not sure how to go about it though. Edited March 21, 2016 by MR_Loyale Quote Link to comment Share on other sites More sharing options...
loyale1993 Posted May 7, 2016 Author Share Posted May 7, 2016 After a few weeks of tinkering and testing I found the issue to be fixed by changing the Coolant Temperature Sensor. Thanks for your help 1 Quote Link to comment Share on other sites More sharing options...
