I'm not sure which sensor you replaced on your Jeep. I will assume you had diagnostics run and replaced a sensor based on a trouble code.

Run self-diagnostics--

Observing the odometer display...

Turn the Key On, Off, On, Off, and On again (three times, just to the point where the dash warning lights come NOT Engine Cranking).

Now diagnostic trouble codes will display where miles is normally displayed in the odometer. Write down these codes. Note- If you lose track of the codes or wish to double/triple check the codes, simply turn the Key Off and start over.

Now clear the codes by disconnecting the negative battery cable for five minutes.

Reconnect the battery cable and check the codes.again. There should not be any codes UNLESS- there is a fault the computer (PCM) recognizes immediately OR you were unsuccessful erasing the codes. IF there are less codes than when you began, the erase was successful but there is still a problem.

To stop nitpicking, I'm going to assume there are no trouble codes displayed after clearing the codes and reconnecting the battery. Now test drive to see if the code comes back. If no codes appear after a few days (approximately 50 miles, although the threshold is more complicated than I need to get into) it appears your repair was successful.

Update us as necessary on your problem.

What would make the speedometer not work on a 1995 jeep cherokee?

A defective speed sensor located on the transfer case will cause this condition. When a new sensor is installed, you must make sure it is indexed correctly or the new sensor will not work either.

Auto zone checked our 2001 jeep grand cherokee laradeo and said the oxygen sensor is going bad. they sold my wife a new one , but how do i no which one to replace with the new one . i check the internet...

If there was a trouble code, the code should tell you which one? bank 1 or bank 2, and or sensor 1 or sensor 2. Bank 1 on a v engine is the bank with number one cylinder. Bank 2 is the other bank. Some sensors are labeled upstream and downstream in relation to the cat, before or after. Upstream is senor 1 and downstream from the cat is sensor 2.
Is it clear as mud?

Misfire codes on my 2000 Jeep Grand Cherokee

Regardless of why the misfire is happening, the shop needs to find and make it right. If you don't return it to them, they can claim it's a new problem, unrelated to the work they did. As I don't have any idea if any sensors were imported with the new engine or if anything was damaged on install, I really can't comment past what I've said.
Hopefully you are dealing with a reputable competent shop...If so, aside from the obvious annoyance, they should definitely take care of the problem for you. I would check fluid levels to make sure that they are good and perhaps even check sensors to make sure they are all on securely but past that I would do nothing more. As far as driving, since you don't know what's wrong, I'd limit driving to only what's necessary but no more.
