Post Need help with 5.4l

Ok here is the scoop, A few weeks ago I had a chain guide break and come through the passenger valve cover. So, I replaced all the timing component's cam phasers, Chains ,Tensioners, plugs etc.. Then today, I took her on her madden voyage and it seems to want to bog down around 50 mph but no check engine light. Does anyone know were my problem may be? I want to think a plug(even though they are brand new) or coil pack. But their may be a chance I could have bent a valve. Any advice on were to start looking?

I'm guessing that by your situation would be a bent valve or a damaged piston.

It runs fine any other time.NO hesitation no ticks knocks or anything just a little injector noise under the hood, But very faint. When it wants to bog down I can either give it gas or let off it and it will straighten out. It only does it when im slowly reaching around 50mph. When I was merging onto the interstate it ran great!!

Have you done anything since you last posted?
Tied new plugs? Or COPs?
If you haven't gotten anything figured out yet, see if you can find a buddy or co worker or family member if they have a good scanner like a snap on or a OTC, then hook it up and repeat your issues and monitor what is misfiring or I nothing is being flagged then i would go and rip into the engine..
Good luck
