Just noticed this but when accelerating lightly a heavy vibration can be felt like your ruining over the lane departure vibration notifiers on the highways. As soon as I let of the gas it goes away, I was cruising at about 50 when I accelerated lightly when it did it. Is this a transmission issue, u-joints, or something else?

Most likely a spark plug and/or coil on plug issue. I use a Bluetooth to OBDII adapter and the Torque Pro app on my phone to record misfires, allows me to figure out which cylinder is the culprit without having to just guess.

Just had all the drivers side coils replaced the check engine is coming on because of the catalyst below threshold. Im guessing there clogged from the bad coils if i bust them out with that cause check engine codes? I just wanted to make sure it wasnt anything driveline related.

driveline bump...have you lubed the splines on your driveshaft..?

Nah just bough the truck I will do that today. Also I have a whining noise coming from the front above 40mph when accelerating I'm wondering if that's related.

Likely a coil. You can be getting a cat efficiency code because fuel isn't being burned and the cat sensor thinks the cat is the problem. The rumble strip sensation you're feeling is probably most prominent at 50-52mph?

Milage on the motor ?? sounds like a Mis-fire condition... plugs need replaced with Motorcraft and do the springs and boots too...

174k they just replaced all the coils and plugs on the drivers side. Doesnt look like they did the passenger side guess i tackle that.



** Just placed a order for the removal tool if one breaks and new plugs and coils
