Hi I own a 2003 Ford F150 Harley Davidson 100th Anniversary Edition (Supercharged 5.4L Engine) My truck was working fine it was time for an oil change so I took it to Goodyear for a full Synthetic Oil Change. I drove my truck home it was fine. 2 days later I went to drive it to work when I crunk it up, it ran fine for a little then it started sputtering I was confused because it never gave me any problems. I started driving and it ran hard while sputtering then the Check Engine Light came on. I then made a u-turn and parked it. What do you think went wrong?

 

You need to read out the OBD2 codes. If you don't want to drive it to a parts store to get them read, buy a code reader, they are not expensive.

 

I will order one today.
