2005 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. |
Just might be the solenoid. Also, check all the vacuum tubes and EGR tube. The easiest way is with a can of carb and choke cleaner. With the engine running, start spraying the cleaner around. When the engine revs when you spray an area, there's a leak. Repair it and try another area.

Replaced both vct solenoids still having same problem. Can find any vacuum leaks. Could I have gotten a bad cam phaser?

No new codes? What does the vct error pid say?

Disconnect the battery and leave it disconnected for 20 to 30 minutes. Reconnect the battery and see if the problem is still present.

will give a try in the morning. Thanks

Not any better :-(
