Knock with stock tune at WOT.

Well all of those things are good too...but the first thing to fix was the O2 sensor but u refused

He drove it out extensively with the ford logger. Battery checks out for charge and alternator was good.

Most mechanics aren't very good at reading datalogs and diagnosing problems...they are overpaid parts changers

Have to agree for the most part, unfortunate .., probably why they are called technicians and not mechanics ... No dis intended to anyone.

I was gonna say that lol I'm really scratching my head at why I get such high knock readings with no audible knock. I need to get some of that high quality electrical tape just tape to the sensor.

Looks like replacing the knock sensor myself would be a no no.

Again...reading datalogs and tuning is a skill that takes a while to get good at...not that I'm an expert but I'm learning and u always will be learning.

U don't get it...u aren't supposed to hear knock...the knock readings aren't knock events but rather the amount of timing needed to be pulled to prevent the knock

 

[curry67]

No one really seems to know what it is. All I've heard is o2 sensor is off.

Honestly with these cars if you get to the point you hear audible knock, your day, week, month, and possibly year is most likely ruined.

Dude u kill me...maybe u just are messing with me...why would u think u need to change a knock sensor?...we already know u have a problem with ur O2 sensor..start there then move on...u don't have a reason to change the knock sensor...it could be real or not...but we know ur 02 sensor is ****....

But yeah throw parts at it aimlessly if u must ur dumber than I thought

Fix the identified problem which is the 02 sensor then proceed...a component that has failed can have a ripple effect because of how many systems rely on each other...don't u get that

 

[ajpturbo]

For a long time I always thought an O2 sensor was a useless thing that just cost money and just tripped check engine lights and had no purpose...that came from people at ur local parts stores and idiots

That is the dumbest thing ever...they are so crucial to a car nowadays...especially when it is a wideband sensor in a boosted car.

Page 8 already!! Definetly start fixing the cheapest component first and proceed from there,peforming the 02 sensor sounds more feasible compared to the knock sensors which is a different story to perform unless you have warranty which i wasnt aware you had and should be your last resort.  Z

 

[ajpturbo]

Lol it's page 8 because he refuses to do what's been recommended lol...I would normally start with the cheaper stuff but in this case there was a clear indicator that pointed to the O2 sensor so that would be my starting point....especially after ksckrew problem that appeared to be the same

 

[FoMoCoSHO]

Should we start an oxygen sensor fund?

Ya know, "We are the World", but for cars....

 

[curry67]

I clearly stated it was getting fixed on warranty I'm just waiting on the part I was just thinking of other things to try.

Just incredible you have to wait a week for a simple part like that!  Ford must really be "lean"ing out on inventory.

 

[curry67]

It's stocked in USA so customs screws it over I'm guessing he said 6 days advisor said 10 days.

Typically that means its a low failure rate item....of course it could just be cause he's in Canuckistan....

 

[SHOdded]

I think it's because of a sudden surge of demand from ... ahem ... EBPF members!

 

[curry67]

The conversion is bad for me now lol

Good conversation, thanks all.
I too have noticed this, sometimes, at 'near' WOT. I hear a loud knock that seems to come from the right passenger side. No codes stored. I've heard it three times in the last year.
