A little background 92 Cherokee XJ 106xxx 3k on new motor 6 inch lift stock gearing.

So I was out wheeling last week and my check engine light came on and it started sputtering like in the video. It's OBD1 so I did the key thing and came up with a code 24 bad TPS. I stopped at Autozone on the way home and picked up a new TPS. I installed it but the problem continued so I replaced it thanks to the lifetime warranty but that didn't work either. I ended up getting one from Jeep but that didn't help either. I did the refresh on all the grounds and even ran new grounds to all the locations under the hood.
Below are the voltages I got when checking them.

The original one
Constant 5.02 vdc
idle .657
Wot 3.715

Autozone one
constant 5.019 vdc
idle .629
wot 3.633

Jeep one
Constant 5.02
idle .706
wot 3.743

Can all of them be bad?
Is there something else I should be checking?

I really need to get this thing running before this weekend any help would be appreciated. Sorry for the crappy vid.

Check your idle air control valve.

 

Idk if 92 had c101 connector but if it did that's something to check out

 

I don't think I have that connector.

 

Well I went to Jeep and ordered another one. Does anyone else have any other ideas what may be causing the problem in the video?

Thanks,

 

It's FIXED! Turns out the purple and white power wire had a short or bad spot. The wire is the power wire for the MAP, TPS and one other sensor, the problem was where the wires split. I just cut out the bad sections and put in some new wire and its running perfect again.

Thanks everyone for your help,

Mark
