While going down the road runs good sometimes then runs ****ty

 

What are you talking about??? The engine running rough? The ride is rough? No one will be even begin to help you with out knowing what you are talking about. What if anything have you done along with some info about the Jeep, year engine.

 

Headlight fluid is low.

 

You gotta change your muffler bearings.

 

Vague post is vague

 

I don't think you're getting a full 1.21 gigawatts... I bet you're running low on Plutonium.

I'd suggest more plutonium, but if you're stranded and on a budget, a lightning rod might let ya' limp it home..

 

I had the same exact problem, cleaned out my canooter valve and now it runs like a champ.

 

Where is this located on the jeep canooter valve

 

Right above the flux capacitor.

 

Didn't they take the flux out and replace it with a gravity-assist propulsion system? I thought they changed in 99.

 

No 1999 has the High Output PowerFlux system. 2000 they changed to a GEM configuration.

 

My bad. I apologize to the OP for giving bad info.

 

I'm not sure on the jeep motors this is all new to me guys

 

Just be more specific. Pretend youre a forensics scientist, and type out for us in tangible, understandable English, all of the symptoms you are having. I.E when my jeep hits 30 mph, I get a violent shake that throws me all over the road but at 40 it's ok...... See? Easy!
