My buddy has a 2005 f-150 with the 5.4 in it. His description is when he pulls up to a light the truck stalls! So stalls at idle but runs fine otherwise. He called me last night and was telling me the car is at the dealer. They replaced the cam angle sensors to fix the issue. They then told him he had shavings in his oil and wanted $5-6000 for a reman motor. I said something didn't sound right but I would have to look into it. Could the motor be bad? I know this is vague but my friend is not to auto savvy and this is all the info. I could get.
