Ok here is my issue, i feel as if i am losing power. Sometimes going down the road the car sputters for a second then ita fine. Also i am burning through gas fast. There is no check engine light and the car shifts fine. Any ideas?

I had the same issue with my 06 4.6, No check engine light ever came on. I changed my spark plugs and coils and fixed my problem. I would start changing plugs maybe?

Maybe a bad injector then? I believe a bad injector doesn't trig a check engine light either.

I tried the injector cleaner it helped a little. I do want to put in larger injectors though
