That would be kinda weird if it had the wrong injectors in it. I think the SVT's are 19 lb. and the non-svt are 17 lb.
I'm pretty sure the SVT injecors are orange-top.
Can you get the codes?? If you get the code and search for the code in either the troubleshooting section or the Duratec maintenance section, you will find quite a bit about what the problem really is.
If they can't give you the codes, Autozone will read them for free. Be sure to write down the number, along with the description of the code (if they give you one).
