Okay I need some help possibly. I have a 2012 Ford F150 with the 5.0. At idle till about 1700 rpm it feels like it has a slight mist and sakes the truck a little bit. After about 1700 1800s moves out and doesn't shake the truck anymore. Does anybody else's truck do that too? Just wondering if I need to take it into the dealer? Please help

 

Bump

 

Some have it and some don't. You're going to waste your time visiting the dealer as they will either not notice it or say it's normal. My 11 has this miss or shudder or whatever you prefer to call it for over 90K miles. It's harmless and I would suggest that you ignore it.

 

Ok. This is the first brand new vehicle I have ever got and it's a huge investment of money. Just trying to take care of it and keep it running the best it can run. I plan on giving it to my son in 12 years when he turns 16. So it's got to stay running and looking good. By then it should have everything he needs on it. Lift tires pushbar lights.

 

Both my 5.0's have a bit of a stumble when idling, but move out smoothly. One has 13K, and the other 8K, and neither have had any problems. You should be fine if it doesn't get any worse. SVT is correct, the service tech would tell you it's normal if he/she doesn't have a code to read.

 

I had the same issue. Put two cans of seafoam in and it purrs like a kitten now.

1 can in the gas tank...ran it, put another one in two tanks later.

Edit... Did it at 50,000 miles
