Anybody good at diagnosing data logs??

Jay.

Checked my TB and every connector I could see with my eyes. All were secure and connected properly.

I think the reason the front o2's weren't reporting in the log I sent you was because it was logged with live link 6.5

If I log through 6.5 right now. It still shows the front o2's not reading but if I log with gen-2 live link the front 02's register perfectly fine.

Do you have a new log with rpm?

Sending it your way now

Ok so what I gather is that o2 were working fine and fuel trims are good. Now it still ran shitty. Have you done a compression check along with base oil pressure?

The tech at the dealer never really said the o2 or fuel trims were not ready just looked weird / off. ? But still reporting.

his first post highlights all of the test he did.

Nick,

Has the intake manifold ever been off of the car?

Was there ever a Boss manifold on the car? If so, do you still have it? If so again, flip it upside down, are all of the port o-rings accounted for?

The SM at the dealer said the tech told him that the o2 readings were weird and it showed that the car had a performance tune on it. That's all he would tell me that the tech said to him. Like I said earlier, the conversation I had with the SM seemed VERY awkward/uncomfortable. Kind of like he wanted to tell me something but he couldn't.

Here's a pic of the compression test I did last week

Pulled the manifold off last week to clean and flush it. Checked all the o rings on the bottom and they were all there in great condition. The manifold had never been pulled prior to that.

Also checked all the injector o rings and made sure they were seated correctly.

Bank 1 LTFT is about 12% lean (1.125), but your bank 1 STFT is within 1% of commanded, it's hovering right around 1.0 in your log, so no real concern there. Bank 2 LTFT is abouit 6% lean at 1.06, but your bank 2 STFT is not logging, again this is a SCT issue.

Your idle is right around 650 which is what is commanded for an auto, widebands are measuring right around .99 vs a commanded of .98, so again nearly perfect.

From a log perspective, I can't see anything wrong with your car.

Uploading a video of the idle from the mufflers right now. Will post as soon as its done.

Here's the video of the idle from the mufflers:

Rough Idle Vid

definitely sounds nothing like a cammed idle, sounds normal until the end it sounds a little weird. Could just be AC compressor surge.

I don't think that sounds bad at all? Kind of sounds normal to me.

Ya.. doesn't sound odd at all.

This is the cammed idle

 

[slvr08gt]

definitely sounds nothing like a cammed idle, sounds extremely normal until the end it sounds a little weird.

Maybe it sounds different in the video than what it sounds like in person. This being my 4th 5.0 in 2 years. I've never had one idle like this.

 

[slvr08gt]

It's also important to note that my car has the stock cats in it right now. When the cat deletes were installed it sounded much more like the ghost cam tune. I got it that it doesn't sound exactly like a ghost cam tune but its not NEARLY as smooth as my car has idled for the last 3 months. That's for sure.

If you notice at the end of my video when I moved over to the passenger side muffler the idle is choppy, you just have to listen closely. With cat deletes it was a lot more easier to distinguish.

AC and heater was not on during the video and it was a cold start for the most part.

I have the Trackey lope idle on my boss and it's a pretty weak lopey idle... And it's much choppier than yours...and I've got stock cats. I didn't hear anything that sounded completely out of the ordinary.

 

[slvr08gt]

Hmmmm.

Don't know what to say honestly. I really don't want to pay the dealer to do a diagnostic on it for them to tell me there is nothing wrong with it again.

 

[slvr08gt]

To all of you that have took the time to help me figure this out. I GREATLY appreciate it. Seems like I have an issue that isn't going to be figured through data logs or a video though.

If I didn't buy this car with the A plan I would have traded it in this week. I guess I'll just have to wait until I hit the 6 month mark in July.

Luckily I already have a buyer lined up for my Paxton kit so I won't have to look at it all the time and know that I will never see it on my car.

Believe this, if I had any thought that my car was driving/idling fine. I would be installing the paxton kit on my car right now.

No one knows your car like you do. I've had some bucking issues on my Boss that I know is there. That being said several people have driven it without feeling it. I say don't give up on finding a solution for the problem. Do you have a shop in town that you trust or at least have a good relationship with? Maybe you could work a deal with a tech to look it over... Not a tech at a Ford dealer though.
