Ok so decided to finally take the new stang to work get going down the road and it starts bucking and sounded like it was back firing so is it misfiring or possibly a bad cop that's what I am thinking but any input would be nice :confused:

Could be a COP. Check your plugs too, maybe one or more is fouled out. That'll let you know what cylinders to look at.

Does it sound like marbles bouncing around in your engine?

No its like its not getting any power and sounds like its back firing but when I drive normal it drives just fine its almost like when the TC is on and your tires spin and it cuts power down but it bucks violently when it does it does that make sense

Need to quit guessing and read your codes.......And ya those COPs could do it. A set of OEM COPs you need to find.

sounds exactly like what my car did with all 3 cops let go one at a time. does the check engine light blink if you force it to misfire while driving? if so you have a misfire, the extra load is normally what makes a weak cop misfire. at least thats my finding. a code reader can pinpoint the cylinder to examine
