I have an 05 f-250 SD 5.4L w/ 130k+/- miles. My CEL came on a cpl months ago and I went to Autozone and got a diag. on it. The codes told me both cat.s were bad and both cam pos sensors were bad. I replaced both cat.s and put 3" dual exhaust .Replaced both cam sensors and now its blubbery when I take off from a dead stop. Its seriously lacking power also. I've been reading some blogs that have led me to thinking about a cleaning with Seafoam and then all new 1 piece plugs . " IF" I can get the crappy stock plugs out in one piece .!!! ???am I on the right track ??? Any help would be greatly appreciated....G

 

I should think you are on the right track if those are the original plugs still in the engine. If there is any doubt about removing broken spark plugs there are several methods suggested to remove the plugs without too much problem. You could check with your local Ford parts dept and they should be able to tell you of your engine has the problem plugs or not.

 

I just got off the phone with my buddy who's a service writer @ a ford dealership.1st thing he told me was to get a complete BG Fuel System cleaning and change my oil every 500 miles untill the engine is completely cleaned up. The BG cleaning will ensure that I can get those rottin plugs out with breaking them off. And using Seafoam in the oil will loosen up the sludge. But I have to "change that oil! Change that oil! change that oil!"
Since the timing is run off the oil pressure and the cam Phasers need at least 22lbs. of pressure to stay in place , it makes since to get it all cleaned and working properly. Thanks again for your reply Hanky ....G

 

Thanks for sharing that info.
As my understanding of the situation is; carbon gets deposited on the lower ends of the plugs and makes them difficult to remove. I have found only certain Ford models have the problem with the plugs and not all triton 3 valve engines are affected. With the VIN my local Ford dealer Parts manager was able to tell me if certain engines weren't affected. It's worth a shot. Saved me lots of trouble.

 

right on , im sending my vin tonight as a matter of fact ,,,who wouldnt love some new injectors too?????????
