My 2011 F150 5.0 was bought used a year ago, and ran like new. A few months ago, several things started acting up.

* clicking at idle. Just a tick-tick-tick-tick kinda like a diesel. I swear it just started, but the dealer tells me it's "normal".

* Oil - I'm "losing" about a half quart a month. No leaks. 1500 miles after a change, it's dingy. (not dirty just brown) Dealer tells me it's "normal" that these trucks consume a little oil and that it will get dirty.

All that I could ignore but this is what bothers me:

The truck seems to struggle, mildly, to maintain speed on hills. It'll drop to 1k rpms before downshifting. Just a pig. Of course if I stomp it to the floor I get a good response, but it is just sluggish and wimpy when driving "normally". Also, when maintaining speed, there's a barely noticeable missing/slipping happening. When I pull a couple thousand pounds it really struggles.

I'm not crazy ... this is happening. Three dealers tell me there's nothing wrong with the truck. After pressing the first dealer they admitted they never drove the truck. The second dealer called me to pick it up because nothing was wrong and also admitted to not having driven it. After I demanded they drive it, they called back still saying nothing is wrong. "The computer would show it if there was a problem." The third dealer has it now, drove it this morning, guess what? "There's nothing wrong, maybe you can come and show us."

I cannot believe the industry has lost the ability to diagnose vehicles beyond what a computer tells them. Do techs not check compressions or ignition or fuel pressure any more? Seems to me a valve issue for example could be the cause of all my symptoms, or fuel delivery, or weak spark, none of which would show up on the freaking computer.

Looking for some guidance or experience with the Coyote 5.0 engine and the 6R80 trans.

After three dealers tell me I'm crazy I'm starting to believe it. :-(

Thanks.

 

No one has had similar issues or advice?

 

Start with the obvious items like testing the fuel pressure, and how old are the spark plugs.
