Cold starting requires turning it over for 4 to 5 seconds before it starts. Sensation of engine lopping for some time.
After heating, up marginal acceleration. After stopping and parking for some time it starts immediately, no hesitation but a very strong gasoline odor is now present.
First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
