Man I get mad if I hit the wrong button and loose a bunch of text. Yes the video works. hirees thismjj

There is a brittle little tube. It comes out of a rubber plug, low on the engine side of the throttle body. It runs back to the firewall, then up to your MAP sensor sort of high up there near center on the firewall. CRUCIAL!! The MAP will tell the ECU to dump fuel with less/no vacuum. Any crack or blockage and it will be pig-rich. (black smoke, fouled black plugs). You can pull the line off the MAP and feel for vacuum with your finger. If it runs!

 

Here ya go:

 

I'll have to check that, don't know if that's causing horrible running or not.

 

As you moved toward the rear of the engine, I could hear an exhaust leak at the manifold gasket. Other than that, just a lot of clatter..nothing I could make out for sure as a misfire. One question....why were you running it with the oil filler cap off?

 

I had just finished changing my oil. Was too lazy to put it back on before taking the video.

 

Bump.

And super slight update.
Whenever I start my jeep when it's cold, it won't run for more than a minute. It'll run for about 30-40 seconds, then it'll just sputter out and die. I'm thinking it's got something to do with fuel/spark.

 

Bump. Anyone else have any ideas?

 

Have you verified your fuel pressure at the fuel rail? You should have 39psi +or- 5psi.

I did this. It says I have 39psi +/-1.

 

Have you looked at the harmonic balancer yet?

 

Not yet. Just recently moved, lots going on.

 

I don't mean for this to sound harsh, but it's quite accurate:

The only way you're gonna find what you're looking for is to GO LOOK!

Around the Jeep that is. In these parts, we call it "noggin pokin".

That's where you use your God given senses to inspect YOUR Jeep for problems. We can only provide you with guidance as to where to poke your noggin.

There's no Silver Bullet cure you're gonna find from a keyboard, mouse and monitor.

 

Yes, I know that. I'm just trying to get ideas of what to look at, that way when I can "noggin poke," I'll know what to look at.

 

I've never heard of "noggin pokin" in my life before now.

And I though we Southerners had some weird terms.

 

Did ya Google it?

Arizona is in the South West...........

Just a corny term I came up with.....
