my truck has been fine. then just the other day i let it idle about 10 mins. to warm up before going to work , idle did not sound smooth, lacks power, vibration less past 2000 rpms. changed fuel fillter, oil&fillter,fuel pressure checked 50psi running. check engine light not on. any help thanks.

I would check the connectors at the valve covers It's possible that there is a bad connection or maybe an under the cover harness giving you a problem to one or more injectors.
