07 Mustang GT Premium Question/Problem

[poohbear]

There is some more.

Since i have seen a few bad o2's; in fact it seems to be an epidemic on some cars. So this month that was on top of my mind considering I have seen a few in this short time... So i wanted to rule it out... A simple is your car tuned? do you have long tubes? If the answer is no... Then i doubt its that... But with all your experience and only seeing 2 bad o2's you wouldn't have thought that..

Factory tune and yes, I have long a tube.... wait... what? hahahahahhaha

Let me educate you then... Oil gets placed in with the fuel and air and lowers the octane value of the charge creating a possible detonation event... Especially in lower tolerance cars... Oil with fuel means a different octane and not in teh direction that would benefit the pistons. Whether its a dilution of fuel or whatever, it doesnt matter; oil in the intake can create knock, knock from a lowering of the octane of the intake charge. You're ASE how do you not know that can happen? Do you understand why an AOS is referred to as cheap motor insurance? This was an example and extreme but like i said before the OP thinks its oil so that was relevant... And no you wouldn't always see oil burning... I see several motors on a regular bassis burning enough oil to make detonation a possibility and recommend an AOS (1 qt between changes when tuned)... Blow by will be relative to how much load you're placing on the car... IE higher revs ect... And when in those higher revs its especially important to be aware and prevent this from happening... I also mentioned that you would at the very least see oil consumption on the sip stick.. Which he is not... You can burn more than a quart every 750 or so and you wouldn't necessarily see it...

AS for oil in his intake track - I meant to look for over average oil in the lines... I shoudl have been more specific... But then again I would think most people would know that on here...

How do you raise duty cycle on the heater in the o2 snesor? Why do you think I asked about the tune and long tubes... This is another example... But then again you think long tubes dont effect o2's... You have obviously never been inside an ecu or dyno have you? Do you know how modern cars work? HOw do long tubes have nothing to do with the sensors? Are you serious? What happens to the sensors when you place logn tubes on? In most cases, they run cooler... I wonder if that has to do with the increased flow? So you raise the duty cycle on the sensors to keep them at temp easier... An o2 sensor isnt all that accurate cold... We have compared the afr corrections on long tubes against and afm-1000 in both cases with additional duty and not... And we we have seen as much as .5 a point off... thats a big deal... I have seen 3 bad o2 sensors this month... ALL CREATED MISS FIRES... I wonder if they created misfires due to afr corrections being off? hmmm you should look that up. You should get out more if you have only seen 2 o2's go bad in 16 years...

I see the need to clean a maf on cars regularly when they have aftermarket filters... Its a cheap easy check... And since I dont know what he has done to the car it was worth mentioning... I clean mine regularly every 6 months or so... And I do see a change in my stored AFR correction averages... IN the direction on would expected from a dirty sensor... This is typical practice especially on a modified car... But then again I did ask what mods he had done if any and that would rule this out...

Ford knock senors are worthless... You need to use det cans to be accurate with the 4.6 motors... the coyotes are different... But your an ASE tech you should know that...

I cant tell if your just trolling me or being serious and just dont know how modern cars work...

EDIT--- Im puling from memory but i think ford runs the heater duty on the o2's at around 30% or some junk... In most cases i see them needing being upped to over 70 ish % with good long tubes...

Well you sure caught me... dang I know nothing about cars I will just shut up now LMAO! Who says I'm ASE I did not lol
sounds like you may want to go and read your post closer, wording is everything. I'm done with this. this is why I mostly stay out of these post.

PS: I am:
ASE master with : L1 and L2 advanced test. L2 advanced diesel T1-8
level 4 chrysler
Master GM

Oh and dynojet certed.

I build a pretty good race engine also

But any fool can take a test... My shop speaks above any test.

Enough of the interweb flexing.

Wow pull your plugs? I wonder if i mentioned to that before? That seams logical thanks for that... I must have no idea what im talking about... GOod thing you were here man... To save from all that miss information i was giving

Says the one that went right to blowby

[poohbear]

I just googled some light reading for you... IT was the first google hit for o2 sensor duty cycles and long tubes... I forgot about them throwing a code as well

http://forums.corral.net/forums/gt-s...s-any-fix.html

So no you are very wrong about sensors and long tubes not effecting each other... You should stop giving out all this misinformation

don't get so butthhurt peter pan

I only talked about blowby to assure him i doubt it was his oil creating the issue... How else would oil create missfires? Did you even see that my number one recommendation was to check the plugs? Maybe I should list things numerically for easy reference and reading for all the ASE techs on here...

Yes that is great and all but you did not go back and read what you typed did you?? you said HEAT cycles not duty...

lol I think you should.


Question master? are you mad that Mello put ASE Certified by my name? I can ask him to take it down.. seeing as I did not put it there.

I will have to put some more miles on the fresh oil to see the full affect this time around. I will update tomorrow.
