hey, thanks everyone, yep its 2011 5.4, the thing is that ford only sells the 6.2L engine in my country, since the 5.4 is no longer avalible, but for introduced the raptor only last year so they never sold the 5.4 model, and this truck was imported by a company to my country (Chile) and i bought it at an auction, because they didnt pay for the truck, the thing is that now it haves some issues, it seems like the injectors or something is not working right, tomorrow im going to the garage and talk to the guy that supposed to fiix it.
