hey guys! i got an 06 lincoln mark lt. 5.4l sohc. i had an aftermarket remote starter put in my truck and a day and a half later my #8 fuel inj gets stuck open. they used a "t-tap" on one of my injector wires. the truck all of a sudden started running like crap so with 78k i figured i should start with spark plugs. not knowing that the FI was the problem at the time i started the truck to see if that helped. as soon as i started it the truck instantly started knocking. no warrantee and ford doesnt wanna know nothin. any input would be greatly appreciated. like a good place near CT to find a reasonably priced crate motor. thanks

 

I'd take it up with the installer. They caused this it sounds like
