You don't seem to fit into that category.
To me, it looks like you may have a case of fraud on your hands, many states do not allow an older engine/emission system to be installed in a newer vehicle.
You can talk to DMV, but they could revoke the registration?...

My club members warmly recommended I submit my problem here because Jeepforum.com is one of the best resource on the web that can be find for Jeep.

I'm under the impression that first I'm judged (in a bad way) because I have been screwed by the dealer and I'm pissed off for it.

But also that I need to "prove" every bit of my assumptions that I have been screwed because I'm almost sure I have a 97/98 engine in my car instead of a '02.

I must admit that it makes me very uncomfortable in regards of this community...
I don't think it is people forcing you to prove your assumptions so much as it is people trying to make sure your assumptions are correct because this is a fairly strange situation. Swapping in the older motor would have required more work than just remove blown motor and drop in the older motor and turn the key, and its enough work that most people aren't going to deal with it when it would be much easier to just buy the correct year motor. I don't think anyone is implying you are lying or trying to insult your intelligence, I think they were just trying to make sure this was in fact the case since this issue is not one that you see every day. Don't be scared off by the forum yet, stick with us and you are going to realize what a wealth of information this place is and how much money, time, and frustration you will be able to save yourself with Jeepforum as a resource

Well..... if it is a 97/98 motor a few things come to mind. First thing I'm thinking is that your truck was stolen or wrecked and put back together after it was totaled by an insurance company.

I would be looking to your DMV to make sure you don't have a salvage or reconstructed title.
If it does in fact have a clean title, I am perplexed about the PCM..... There is no way in any state that it will pass a smog test due to the mis-orientation of the VIN to the PCM unless it was flashed. In any case.... You appear to have a strong case of dealer fraud and I would be dialing up a lawyer fast.

Silmar, there is tons of useful knowledge here. you must remember though, there are no gaurantees of accuracy or honesty. We are enthusiasts like you, the info you obtain here is worth exactly what you paid for it. My opinions included.

With that out of the way, I dont think you have a motor swap case here, I truly think you have a TITLE swap/rebuilder job on your hands. look st your tailgate does it have a big plastic 6"X6" vent assembly behind the spare? if so its an 01 and older tailgate. correct me if im wrong folks.

Also lets collaborate and determine what year the rest of his TJ is. Tub, Mirrors, Top, Wheels, Dash Trim, Etc. are all tell tales of changes thru the years.

the engine trouble is most likely the 2 upstream o2 sensors

they dial in the fuel mixture and if theyre failing they can run your engine rich causing it to "sputter"

Do the 4.0 engine blocks have the VIN or some identifying number stamped on the block that the OP could reference?

@ Knuckelhead
The first two pictures are the "Ignition Coil" plug I was talking about previously. First the detail, second picture were it is located.

@Knuckelhead & Robet J. Yates
See below three pictures of my engine. So is it a '02 or not?

@Knuckelhead & Robet J. Yates
Another picture showing some cut and repaired wires. The CPU unit (I don't know if we can see if it has been flashed or not just by looking at it). Also, I took a picture of the door sticker showing it's an '02.
I will go tomorrow to check at the DMW and let you know...

@lostone73
I attached a front and back picture to help determine the year of my car if it helps. I do not have any vent on the tailgate.

@lKrux
If it's the O2 sensors, will the problem be present all the time or only when I tried to go over 4,000 rpm. Because the engine runs perfectly fine, until I try to reach 4,000 rpm or above.

@dirt_j00
I tried to read it but couldn't. I can read 903MX1 then maybe a 2 but that's all...

Let me know if you need more details and/or pictures.

Thanks a lot to all for trying to help me!

I expected to be wrong, just giving an example of how we could help determine what conglomeration of parts Silmar has.

OK, so far everybody seems to agree it's a 97/98 engine correct?

I was actually thinking about going to my Jeep dealer, tomorrow, and ask him to check the engine number and let me know if it was the original one. If not, I'm guessing they can find which year it was built correct?

I also check the VIN number on the car and it is identical on the door sticker, rivets on the dash are untouched and it match the Jeep stickers everywhere else on the car (tailgate, hood, both side of the engine compartment...) and on the documents from the dealer. Then I realize all these places are on the BODY of the car.
So I did some research but cannot find where the VIN is stamped on the frame. I find a lot of descriptions for a CJ but nothing on the TJ. So where can I find it on the frame?

Edit: I do have a question. Robert mentioned it will be a lot of work to change the engine from '02 to 97/98. What about keeping the frame, the engine and change the body? Do I have a way to check if the frame is a 97/98? I read here and there that '02 have mini CAT. How they look like?

IMO that is not the engine that came with the year of the sticker on your Jeep. Another thing to look at is the part number on the PCM. Take that number and see what it matches up to for what year?
If you go to DMV, they might revoke the registration...

That's another point, does it have a 2 piece exhaust manifold? All 2001 and newer have that manifold with the mini cats mounted in the exhaust pipe below it...
