Hi Guys, i have intermittent sputtering, this normally happens when accelerating especially when going up a long incline at at between 50-60mph. the engine continues to sputter until i turn off the ingintion, when i restart it generally goes away, i get no error messages on the dash display, the yellow engine warning light does come on, but after a few restarts and driving without sputtering it does go away. my spark plugs and coils got replaced 2 months ago, so i assume the issue is not with them.
if i do not put to much pressure on the accelerator, the issue does not come up, but a sudden fuel demand does bring the issue to light.

i am thinking mabey the MAF or fuel pump, any thoughts.

thanks...

Sounds like misfire. Get the codes read.
