Sputtering/loss of power in 1st-3rd gear

I've got 1994 wrangler with the 4.0 HO. It's lifted And has big tires. Anyways if I'm at low rpms and just cruising through town in a low gear it kinda sputters and makes the whole jeep shake. I just bought it and it's alway done this. I did a full tube up and it helped but it still sputters. It's got gears and a locker too. Anything helps thank you

The gearing has no direct electrical connection so I am wondering if you are dealing with a rpm issue or loading issue. Does it do it all the way through the gear range in 1/3? Start by checking your fault codes and post back what you get.

It's 1st gear and sometimes 2nd and sometimes even 3rd. To be honest I think it's just my inexperience of driving it I mean I just bought it. And I'm at work so I can't check the codes yet. But It might be just be not giving it enough gas but I'm not very experienced with jeeps it's my First one

Yeah I checked it out. That's awesome that I don't need a computer! Haha thanks for that. I'll do it right when I get off. Also though I should start a new thread but do you know much about leef springs?

I am a electrical kind of person. There are many many many people here that know the suspensions better then I do. Post it up to a new thread. The Thread title will get you headed in the right direction by getting the peoples attention that do.

I think your 24 is a 33. You should always see 12, 33, and 55. It sounds ok.

Are you seeing a 33? You always, and I do mean always get a 33. Maybe video it to youtube and post a link so I can see the flashes.

It gives a 12 24 and a 55 to end. It flashes twice fast then a break then 4 quick flashes. I read online that 24 means the tps sensor. I then googled and found a forum with guys having the same problem as me and it was there tps sensor
