P2195 and p2196 codes popped up recently on 2003 Explorer 4.0
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?

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.

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.

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

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.

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.

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?

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.
