I really need some help. It seems as though my local dealerships are lost. My truck is bogging and has a 'guttural' sound when accelerating. This is especially true up to about 4000 rpm. It will not accel. It actually sounds like it is accelerating from hell but when look at the rpm.. its not changing, and the speed is not increasing. I cannot safely pass at all. Ford replaced the timing chain, cam phasers, o2 sensors, cats, and any sensors associated with this. I have to run my peformance setting JUST to get it to act normal.. not anywheres like a programmer is attached. After the EXPENSIVE repairs didn't fix, Ford dealership tried blaming the plugs even when I insisted new plugs. They have tried to blame everything and want me to pay.. tried blaming the mass air flow meter stating it wasnt factory (until the saw Ford stamped on it), the idiots, the computer, and the Gryphon computer, even though it was not used at all after the repair and couldnt even drive off the lot . They want me to just keep pitching out monies till they find it. It is not throwing any codes ande being as it runs like it should stock WITH the performance setting, I would assume that it isn't a misfire. Please help.. cannot find anything on the web related to this. 2005 f150 5.4l

 

After my only other local checked my truck (they had it for two days and stated worked on it three hours), they are lost too. Said they would have to start charging me the '$90' an hour service fee till they could find what is wrong. So, after paying $1800 for cam phasers and all the above mentioned, two diagnostic fees at other dealership to try to find problem ($180), paying $90 to have them turn on the cruise control in the PCM that the first dealer turned off ($90), a new starter where the first dealership didnt tighten when replacing the cats($192), 8 trips to the dealerships... I officially hate Ford. They stated today they need to 'put stock tires on it to see if it still acts up'. I only have 33's! UGH! So getting close to $2300 and truck still runs exactly the same. This dealership wants to get the Ford engineer involved but no idea when he/she will be there or how much that will cost. Please.. is there a Ford engineer out there who might can help! BTW the O2 sensors where replaced with the new cats.

 

Have they checked the injectors to see if they are leaking?

 

Wow dude I thought I had problems with my truck. Are these techs certified lol.... No but really that sucks your going through this. I can't imagine what else it could be. Sounds like they have replaced dam near everything.

 

From what I have been told, yes they have. But the one dealership also told me I needed new flywheel when I didn't. I have asked them to pull a vacuum check but can't seem to get them to do this. I am at the point where I want to sell it but I am an educator and looks like I am going to be one of those who are laid off as I teach technology. Good times right now. LOL. Thanks for the responses.
