06 f150 5.4 triton. Knocking and rough running

Asked by Mar 30, 2016 at 12:40 AM about the 2006 Ford F-150 XL 4WD

Question type: Maintenance & Repair

Okay, so my f150 5.4 w/ 176000 miles has a
tapping sound that has gotten worse. I have
change my plugs and bad coils, Change oil on time,
and just had a full engine diagnostics done.
Nothing is wrong with anything internal. They said
it sounds like valve chatter, maybe sludge built up.
I also had po420-po430 codes a while back, I ran
emissions cleaner in my gas and the CEL is gone. I
know that doesnt mean my cars are good now.
  When I am at a constant speed and hit the gas it
bogs down and jumps  to accelerate. With over
drive off, it does better. Maybe cause higher rpm?..
Im puzzled o. How I can stop the tapping and fix
the bogging issue

If your vehicle has SOHCs tensioners it cold be the problem. A 4.0 I had blew because of that problem. As for the bogging down, it could be something as simple as a tuneup, clogged injectors, or fuel related. It's going to be a process of elimination.

Thank you for your input, also the passenger side exhaust is more muffled sounding than the drivers side. Big tone difference, its true duals.
