Actual code numbers may help us here. If you are going by the codes I would start looking into the oxegon sensor problems though.

How are the tune-up things on your jeep, spark plugs, wires, filters etc?

I will check my plug wire's and oxygen sensor's.

First off thank's for your help.That's is why I am confused about.There's no check eng light is on and no code but it's ruining worst after I did the tb clean.I just put the scanner and those are the thing's it is showing.Just did oil changed spark plug's clean my air filter k&n.

Your cat is probably plugged.

I am inclined to agree with Country Boy. Even though you aren't getting a check engine light, a plugged Cat will cause the problems you say you are having. What did you use to clean the TB? Some of them will do damage to the Cat as will some injector cleaners. Also as earlier said it would help if you refered to the code numbers that you got. Not trying to insult your intelligence, but, if you disconnected any of the wires onthe TB, did you put them back? Just trying to help...

I used tb cleaner and also disconnected the battery before removing the tb I made sure I reconnected everything.If I had any po code that would help.So any idea's what I can do first,what can I do about the cat.Thank's for your advice.

A plugged cat will get extemely hot(sometimes glowing). They often give off an oder like burnt eggs or sulpher. If you can get it to run and are able to drive it for for a bit, check the floorboard inside on the passenger side above the cat. A bad cat will have the floor very warm or hot. Sorry I misunderstood about the codes. That would really help if you could get any, but if it turns out to be the cat, it will have to be replaced. Another thing - the cat will also cause you to lose power when you try to accellorate('cuse the spelling). It can also make it jerk and hesitate. There are other problems that can cause this which is why it would help if we could get some codes.

IF in fact it is your cat, this is a forum members business. He supplies exhaust parts for cheap. The cat you need should be 2.5" IN and OUT.

This is his forum for his exhaust kits and what not.
