No. Why? Wouldn't the connectors be different?

 

Allright new injectors it is .. that must be the reason its not running good

 

What did the old plugs look like ?

 

Black as tar. But it had sat for 5 years so who knows how old they are

 

It sat 5 years? Man, that IS a long time. I thought my problem was old O rings, but soon enough I had more leaks than when I started. The stock injectors really where crap. $480 a set then for the replacements.

This is the thread about the (ends up), Liberty injectors.:

has anybody actually tried the 4 hole injectors to see if they do have better mileage?

 

www.precisionautoinjectors.com for about $100. 4 hole injectors flow-matched with new o-rings and guaranteed.

Jeeptunes: No real mileage increase but better throttle response and smoother idle.

The real concern is getting rid of the stock ones as they
can burn your Jeep to the ground!!!

 

X2 on burning. Get rid of the stock ones. They are junk. Consider 703s if you plan hp upgrades.
I ran the liberty injectors after flow testing the stock and the703s. They do save gas. I am also the person selling extras that I have.

 

I took the fuel rail off and tried cleaning injectors. Its running pretty rough. I tried holding it at a constant Rpm of 2k and it was missing bad. Plus its running really rich. Smells like gas bad when running. I'm worried its not the fuel injectors. After seating the fuel rail better the moisture spot around the injector did go away

 

Have you checked the hose/pipe from the throttle body to the MAP sensor?

 

I checked the throttle body and everything is hooked up as I can see

 

How about the hose/piping to the MAP sensor? Any vacuum leaks can cause a loss of vacuum to the MAP which will result in low vacuum to the sensor and hence a rich mixture. Get a can of throttle body cleaner and spray all suspected intake areas with the engine running. When you hit a vacuum leak you'll know it as the idle speed will change drastically.

 

I didn't see any hose or piping on throttle body

 

I checked for all ports and I only saw electric sensors. I didn't see a place for piping

 

Sounds like that's your problem then. You must have a hose/pipe from the passenger side of the TB running up to the MAP sensor on the firewall directly behind the engine.....
