Bad Gas Mileage After Top-end Rebuild

[Bill2001gt]

Pull the valve covers, set crank pully to top dead center, and verify both cams line up to the proper marks. That is horrible gas mileage, with my 4.10's and stock 04gt I get 18mpg average, and that is full throttle half the time i am driving if not more, and I red line it everyday

Thanks for the input I hope that's the last ditch effort I did put a new throttle positioning sensor on the other was calibrated wrong because they taking the slack out of the throttle cable my gas mileage is about 16 MPG, and I got 22 on a highway run but I do have a low idle Miss so I'm going to put new coils and plugs in hoping that she'll take care of it I sure appreciate all the input from everybody thanks again

Thanks guys. I put a new set of GTR cop's on and new Autolite plugs I got add up to 15 and a half miles per gallon and I got 0 to 60 in about 6.5 but there still seems to be Miss at idle and I think I need better gas mileage than15 and a half, so I'm taking it back to the rebuild guy and have him check the timing gears set up. There is also a vibration between 40-50 mph ???? I had my tires balanced twice and I'm going to try some Dr tranny just in case but I think it's tied to the miss fire in the engine
