Ive posted in a few other threads, and facebook and asked everyone i know, i cannot figure out this issue ive run into, so i installed catless downpipes and its a great kit, great material, blah blah blah, however i went to log for my tuner and we noticed when i go wide open throttle, my afrs flatline at either 0.00 across the board or they freeze at a set rating, only in bank one though... soo i lifted back up found a exhaust leak and changed both bank 1 02 sensors, still nothing... im very confused... now when i go back to stock, it runs like i have a three bar map in, idles good, but when you give it gas it falls on its face... i need help gentlemen! IM LOST smdh
Whose downpipes do you have installed? Was the leak at the flanges? One of the cures is to doublegasket, and the other to retighten the bolts a few days after installation. Or both. Are you sure the wiring isn't damaged on the O2 sensors? The tune also needs to tune out the rear O2s in this case. Who is your tuner?
Have you logged it stock? I would and see if the O2s are still off...

I did indeed, i didnt moniter afrs because when i got into it it broke up real bad and was running like s***...

Just a suggestion, you will probably have an easier time sorting through responses if you keep your info in a single thread as opposed to spreading them out across multiple forums. I've had questions posted across multiple threads before, and it became a nightmare to manage the crossover. If you so choose, the moderators can merge your threads to make things easier to track.
IMHO, the forum will be a better venue to work through your issue as compared to FB.
Well..if it was running fine before the switch, I would double check all the connectors on all four O2's... Also, and DTCs reporting? I know the wideband sensors can be a b*tch to get out and some shops heat them up causing them to fail.... Pipes shouldn't matter...

I didnt mean to spread it throughout the forum, im just a newbie when it comes to forums and im freaking out about this issue lol, i prefer facebook due to the notifications and ease of mobile use
Btw they are stainless works catless down pipes, the leak was at the flange, the bolts were retightened and i will have to check all the 02 connections asap

No worries. :) The forum indexing is nice, and it's easy to attach logs, pictures, etc, and it is also helpful for future members to search and learn. There are some brilliant peeps on here that will help get you straightened out.
You should check near the flanges even now that you tightened the bolts...there is a inner weld for the flange that cracks...early on SW wasnt welding the outside of the tube....mine were cracked and needed repaired
Who installed the DP? and what kind of lift did they use and hopefully they did not damage anything underneath. Did they open the hood?. Z
BTW merged your Topics together,less clutter. Z

That explains the difference in welds I saw! Just got your old pipes installed today, my god the car pulls hard now.
On my OEM pieces, there was one rear flange with a double gasket, and one with a single. I kept them as it was. Put on my downpipe tune (among other things), and ran the car around town. No issues that I noticed, except that it pulls harder than expected.
I like to use a tab of RTV silicone around the gaskets for a secure leak free system. Z
Are you sure you put the correct replacement 02 sensor in? Did you maybe put a downstream sensor in the primary sensor location?
Your bank 1 is locked in at .97 which would be really lean...Your STFT's are reading the same for both banks which is odd because bank 1 is showing measured afr .97
It seems that maybe the ECU kicked into a mode where maybe it is basing fueling on bank 2 because there is something still clearly wrong with bank 1
You should also be logging LAMBSE. That will tell you what the ECU is targeting for afr
Heres another one let me know if lambse is included, im on mobile so i cant check for myself, we used a 2 post lift, and yes the hood was opened to connect 02s, all 02s are in the correct location, i did however replace the frontside wideband with a back side wideband on accident, however this was after the issue, and the only difference was the size, so i cant imagine that is making an effect, also am i correct to assume the front side of the motor is bank 1?
You still have that rear sensor in there dont you?
Yes all oxygen sensors are in
I mean did you leave that rear 02 sensor in the primary 02 location?
Im sorry, We are misunderstanding eachother, the primary wideband 02 is in the correct position
I wont be able to look til later but i woukd say 2 options..return to stock and log and or change that primary 02 that is locked...but i think you said you got a new one already....was it a motorcraft exact replacement?
No problem i apprieciate your help, you have no idea, it is the exact fit from autozone, it is not the o.e motorcraft product
Bank1 is firewall side, Bank2 is radiator side. Pre-cat O2s are widebands, post-cat O2s are narrowbands.
Do you still have the old ones?...might be worth a try
With 02 sensors and fuel iniectors i would always go exact oem...the lambda vs voltage scale with other 02 sensors may not be the same and if not the ecu will interpret the signal differently
Theres a problem lol i changed the front side 02s however the factory 02s are way out of my budget at the moment, i will try swapping them for new and see of that works

You could try RockAuto.com and get a 5% discount on OEM sensors. Might not be too different for what you pay for aftermarket at a local store.
Cutting costs now may cost more time/money later.

Ain't that the truth.
That statement should be quoted and placed on the forum's front page.
Well articulated!

Hmmm how cheap? Make sure they are widebands.... There is a huge difference in price between basic and wideband..
Also, when I was chasing down an issue I swapped out the oem widebands with Bosch... And they worked great..

So your bank one looks like it has a standard O2 sensor... it reads two settings... rich and lean... like a normal O2 not a wideband... I would double check that the wideband in bank one is correct.
Looks like AutoZones cheapest wideband is going be about $100 after looking... so if you are paying significantly less than that, you are not getting a wideband I suspect...
Your Short Term Fuel Trim is slightly interesting... it is identical for both banks through the entire run.. usually there is a small variance.. like .01 or so difference at times if its tuned well... maybe nothing.. but not sure how its determining how much to fuel to add or take away on bank one without a good reading.. fuel trims might be being built off the only wideband as a failsafe if one is not reading correctly? Dunno...

Seems about right... Dunno... Your bank one is not reading right in that data log you posted.. it's reading like a narrowband...
Sent from my Nexus 6P using Tapatalk
dont the narrow bands have different plugs than the wide so they cant be mixed up??
im having similar issues with identical readings
my downpipes are unleashed 3 inch and i have 0 leaks anywhere
Yes but you never posted a datalog....its hard to say if your actual sensors were the problem or the actual wires were a problem based on the dtc you threw....you said you bought new sensors but it seemed like the wires could be a problem....try and post the log that made think something was wrong
