Just recently rebuilt a 5.4 3v for my 2005 f150 ran fine for a week but it suddenly started running rough fixed a few codes but for some reason can not shake power issues. It is sluggish on take off then it runs great between shifting gears but when it shifts the truck bogs down and pops. Any idea what i could do to fix this issue

 

What brand of phasers did you use?

 

didnt use aftermarket I bought the kit from ford but had to go aftermarket for the Oil pump

 

That's what we recommend - OEM timing components and a Melling oil pump, sounds like you did it right.

 

Can you post the exact codes? Please.

 

Ok hooked it to live data and the timing is over retarding on the throttle instead of advancing. Any suggestions?

 

Does it return a P-code?

 

I didnt think to look the codes that show is crankshaft sensor

 

What is the numeric P-code?
