4.8 seems off a bit
2008 . It's a loaded 3/4 ton and seems normal except for 2 things. MPG on the trip computer dropped by 1 MPG. Idle has been a bit rougher lately. Are these prone to things like intake leaks? No SES light anyways. I haven't had codes checked.

Could be vacuum leak or fouled injector. I'd run some Chevron Techron or Lucas fuel injector cleaner down the gas tank.
