Well I think i mightve fixed the stuttering/shuttering. I changed all the spark plugs on the driver side (2 of them covered in oil), took it for a spin, and "she" pulled stronger then ever, even uphill in the 40-50mph range (which was when the stuttering was worse).

Ill do some more test runs for the next couple days to confirm , hopefully this is an end to this issue, for now smile
