2005 f150 rough idle and loss of power
Hello all
Joined the forum with hopes of getting my f150 running right so i can enjoy it like everyone else does. I have a 2005 Ford f150 with a 5.4 auto. It has a rough idle(shakes the truck), very little power, and poor gas mileage. Randomly It will throw a code for misfire on 1 and/or 3 on start up only. It does seem to perform better within the first few of starting but dies right off after that. In fact i got stuck in the snow the other day and it could barely break the tires loose to try and get it out (almost put in 4low cause i didn't want to hurt the trans) I have replaced: Cats Fuel pump Plugs (motorcraft) Random Coils Did the timing chains and phasers MAF All new injectors Intake gasket Was at my mechanics and had a scanner on it and at idle the 1-4 cylinders are all show a negative cylinder contribution. But when you rev it up they all go to 0 across the board. Was kind of thinking about the Variable Timing solenoid. Any advice would be greatly appreciated. |
Sounds like your throttle body needs rebuilt
