P2195 and p2196 codes popped up recently on 2003 Explorer 4.0

So, after you changed the sensor, you cleared the codes and the P2195 still came back?

Also, on the bucking and jerking, I don't remember that from the original post. Do you know where to find Mode 6 data in your scan tool? It sounds like you're dealing with a misfire as far as that is concerned?

No when I sprayed B12 into throttle body I got a map or maf code.
I changed my oil just now.
It's been bucking or jerking and o2 sensor could cause that too based on Google. I was going to ask about wires tonight if it would trigger a misfire code. Acceleration seems to be better with fuel filter and 1 new o2 sensor. I changed wires and plugs last year but maybe the autozone wire has an issue. Plug wides have a warranty.
I may change the other upstream o2 sensor later and plugs n wires again. I took live data video today driving.
I fieled yesterday and today and was showing 8mpg average.
I believe some of my fuel trims are negative.

I don't think you need to go changing the other upstream O2 sensor. The fuel trims the you've posted lately look pretty good. A decent range is 0, +/-10%, and you were right there from what I've seen.

Can you check to see if your scanner has the option of looking at something called mode$06 data? It can help you identify which cylinder is misfiring.

Let me look online later for the manual for your scan tool. I want to see if it says anywhere if your tool can access mode 06. I would guess it can since it's part of the generic side. If so, we should be able to see what cylinder has misfires, if any.

What about video I posted? I would go to each o2 then gun it. At end I scrolled while idling.

Honestly, I haven't had time to watch the video. I'm swamped at work.

Are you still getting the p2195? If not, that's a good thing and we can move on to whatever other problem you have.

One other question. I know you said you replaced the muffler. You did mean the muffler and not the cat, correct? The reason I ask is because P2195 can sometimes be caused be exhaust leaks near the sensor. I've seen other lean codes (P0171,174) on Fords that have leaking exhaust manifolds. It's not always a true 'lean' condition, just what is perceived as lean.

Yes replaced with Thrush turbo muffler from AutoZone. Maybe the o2 sensor fixed. And I dont fully understand live data. I though the downstream showed 0 a time or two while running s1b1 after I replaced the upstream s1b1 (video)

Ok, so it looks like you may have your code fixed.

What drivability symptoms are you still having? Do you still feel a misfire? Can you describe what it feels like, when it happens, rpm range, speed, etc?

Don't feel bad about not fully understanding data. It takes a lot of practice. Keep studying data after you get this problem fixed. It's hard to learn when your under the gun. Start learning what good data is to help you know what's not good.

Like a bucking or jerking.
Is replacing spark plugs after 16 to 17000 miles too soon? Today was 15 mpg average.
Thinking about replacing other upstream o2 sensor and spark plugs again after 16000 miles. I havent messed with rotor. Changed oligs and wores last year about 16000 miles ago.

If you didn't use the OE Motorcraft plug, then I would put those in. If you did use OE plugs, then leave them alone.

Unless your fuel trims dictate it or you set a code, don't change the O2 sensor. \

What you're describing sounds like an ignition misfire, which is really why I was hoping your scan tool had Mode 06 data. It doesn't, so that makes finding the culprit cylinder a bit harder, and your tool doesn't have the power balance test either. You don't have a scope do you?

Sorry notifications are late to me. I just replaced drive side with Bosch double platinum plugs. Autozone and Ford said motorcraft double platinum but double platinum not an option in motorcraft. I just came inside from installing 3 left driver side cylinder 4,5,and 6 with Bosch.
This morning I installed flex exhaust pipe to connect my muffler (new) back to the rear tailpipe so its quieter.
I plan to do plugs 1, 2 and 3 later or tomorrow and replace wires again tomorrow. If it's not running great after this I will shoot cat converter with an infrared thermometer laser and if that goes good I will be leaning towards maybe it's the transmission

I think you said if not motorcraft I should leave plugs alone but I didn't get the notification. I'm labeling the old plugs so pics of old plugs can be likely tomorrow.
