So my jeep was fixed by my mechanic fixed the drive shaft and had to replace two o2 sensors. I still have the check engine light on and he said for me to drive the truck as I do lately because he had to reset the computer and that way I can take it to the emissions. I never heard of that please let me know your thoughts.

 

Yes you will need to drive te vehicle to set the readiness monitors. CEL must be cleared to go away, for most codes.

What code is being reported still?

 

check engine light looks like a caburator.

 

lol in my eyes but yes it's an orange

 

Um... What's the code?

I know what a CEL looks like

 

I took it to emission it was rejected, the lady at emissions says I have to drive the car a few days since my mechanic reset the computer in the truck. My mechanic said its a code 5 misfire

 

OBD-II codes are in the form of P0305 - that's cyl 5 misfire

 

Code 5, or P0305 cylinder 5 misfire?
I don't think OBDII has a code 5.

 

Beat me to it.

 

exactly, so basically they said to drive it around for a few days but my mechanic said he will personally take it. I have a 7day permit since my plate expired in Chicago.

 

Exactly what? And I thought they told you to drive it around for a few days, a few days ago.
Sounds like your mechanic is taking care of it.

 

yes he said it might be a coil or something but he replaced all the sensors and did a reset on the computer

 

My mechanic changed the vacuum connected to canister but he changed o2 sensors all of them I still get a check engine light wtf now he says I should change ignition cool really

 

Yes really.

You had said before he thought it might be an issue, so what's the big surprise here?

He's diagnosing the issue, and sometimes to do that you need to follow a path. Sounds to me like he's following the right path, taking care of smaller, inexpensive items first, and going from there. Sometimes automotive work isn't cut and dry, as a matter of fact, just the opposite. Usually one problem has many different factors to it. Calm down. He's doing the right thing by checking the low cost ones first, and believe it or not, he's doing that for your benefit. Always check the easy stuff first, as it's usually the least expensive.

Also, you have never posted any info on your ride...what year, what config, etc....it will help others here in trying to diagnose your issue.
