Pinging and rattling 5.0L
Hello All,
Had to take the F1 into the dealership yesterday for a rattling noise that I presumed was a belt tensioner of sorts. Turns out, the tech claims it's pinging caused by the EDGE programmer I have. He says the engine is running lean (I'm running Program 1 for economy which is believable)but that I also have carbon build-up as well. Ordinarily I wouldn't think this strange but I had my truck in the dealership at the first of the year for the notorious 5.0L "knock" (which also still persists) and they recommended the carbon clean then. So two carbon cleans at $170 each within a year!
I guess my question is, does this seem normal? I've had nothing but issues with this motor from day 2 (Day 1 you couldn't have convinced me of any issues as I was on cloud-nine). I love the truck but I'm naturally concerned about longevity.
Your thoughts are appreciated. And if there are any Ford Reps lurking, your input would be appreciated as well!

Interesting. Very interesting indeed.
I have nothing to contribute as I'm not entirely educated on the effects of running lean/rich and what could cause it on a modern engine. But I subbed for the result. I personally think the tune could be part of the problem and I wholeheartedly recommend going back to stock and evaluating it from there.
If you can afford it, I'd trade the POS in. I personally can't afford to trade my problematic 2011 in and I feel like crap because of it. Ford really screwed up on the 2011's.

Make sure you are running the recommended octane for the tune. Even if it calls for 87, step it up to the highest available fuel, and see if that fixes your problem. Secondly, excess carbon build up in the combustion chamber can lead to detonation because of the irregularities of heat build up (hot spots). Carbon build up is present when cheap gas is used btw, so change to a more quality fuel.

Or return the tune to stock and see if it goes away.

In addition to gasoline quality, octane, etc. you may want to consider installing an oil catch can - installs inline of the PVC system to catch oil vapors.
PVC oil vapors will lower the octane in the cylinder, and since you're trying to run-on-the-edge of the how-low-can-you-go-octane before the knock sensor can't compensate, this should help.
In addition ... It will/should lower cylinder/head carbon build-up (which raises compression ratio).

Go back to factory tune before U damage UR motor and put E85 thru it for a couple of tanks.

I had the same problem with my old chevy 6.2 with the edge in it. I highly recommend to never put it in again and go with a custome tune somewhere else. I'm personally not a fan of Walmart tunes but that's my opinion.
