Either one or two of my cylinders aren't firing, what could be the problem? Spark plugs?

 

Plugs, wires, injectors, valves, distributor, rotor, random fluctuations in the space time continuum...

Need some more details about year, engine, what codes it might be throwing, and any other symptoms, and we can probably help you narrow it down.

 

My finger hurts sometimes, what could be causing this?


You get the point?

 

Flux capacitor ? Need more info

 

We know the answer to that....

It's where you keep putting it.....

BTW, how long is a piece of string?

 

On a more serious note:

Thanks for your post.

We’re here to help, but you must understand that all Jeeps are not the same.
In order for us to give you more accurate advice and help, we must know the following, as applicable, along with detailed information as to the symptoms/problems etc:

Year
Model
Engine
Transmission
Transfer case

 

2000
4.0 straight 6
231 t-case

It's not throwing any codes

 

2000
4.0 straight 6

It's not throwing any codes

 

How have you determined that 2 of the cylinders are not firing?

 

You can't hardly fart next to a 2000 Jeep without it throwing a code. If you had cylinders not firing you would have a CEL staring you in the face.

 

That's what I was thinking. I quit going to the Taco Bell drive-thru for exactly that reason.

 

Honestly I don't know much about motors, but my dad said he can hear when it's missing out

 

No disrespect to your dad or his auditory diagnosis but like others have said, if it weren't firing on 33% of it's cylinders... there would be a code. Something as simple as forgetting your gas cap will throw a code so if entire combustion chambers are just along for the ride...

 

There's no codes or engine light, but either way there is something wrong with the engine...2 days ago it started to sound like complete crap and it runs really bad

 

Literally right as I posted that last post the engine light popped on
