This rarely happens but in the past two days, at any speed above 30 really, when I push on the accelerator, it feels like it's jerking in the front. Happens about 3-4 times a day. I have a 2004 5.4L v8.

 

Well I got it checked out by Ford. Turns out it was the coil in the engine. Just thought I would say this so if anyone else has this problem.

 

LOL and ford coil packs strike again! Thanks for the info!

 

Lol yeah. This is actually the first mojor problem my truck has had.

 

all i did was change my spark plugs. its fixed the problem

 

My truck was doing this right before I sold it.. Super uneasy feeling

 

Hahahaha mine has been doing this for 3 months it was so bad I thought it was the trans. Lol worst misfire I have ever felt in my entire life. I just changed my plugs after the diagnosis and no more missfire, haven't changed the coil yet so it was the plug. Don't forget to change your plug on your bad cylinder too. I replaced all 8 coils and plugs. $$$$$$$$

Go to ebay. I just bought 8 DG511 coils for 225 hurray for shady ford employees!

 

For future reference, these are the same as Motorcraft coils and you get two spares:

Well sounds like mine was pretty simple. I was just gonna do a tune and replace spark plugs since they never have been but decided to wait.
