5.4L rough at 1600 rpm
I have a 2010 FX4 with a little over 8k miles. After about 5k I started to notice that the engine has a rough spot right around 1600 rpm in at least the first 3 gears. Once in a while I notice it in the top 3 gears. I haven't posted about this because I just ordered a SCT tuner thinking that might help. It hasn't helped or made it worse.
Has anyone else noticed this? Has it gone away on your truck? It doesn't seem to be a problem, just annoying in rush hour traffic. TIA
