Gotta bunch of symptoms, figured it would be more likey be one issue as opposed to a bunch.

-Loss of Gas millage
-turns over fine but takes forever to start
-runs rich
-Stalls only when it comes down from the front axle being articulated way more than normal (doesnt matter which side is higher)
-loss of power upon acceleration
-never stalls but idle drops way down when you accelerate from a dead stop.
-runs normal at a steady speed
-Idles normal

One person suggested the Fuel Preasure Regulator
He also said to smell the oil to see if there is gas in it.

What do you guys think?

I know it doesnt really go with your symptoms but a few things that come to mind are: plugs, distributor cap, oxygen sensor, Fuel pump. Loss of power can be attributed to low compression, but I dont think thats part of your problem...

Edit: maybe you should check your MAT sensor too, If its bad it will make it run really rich (tells the computer its -42* out)

 

Engine only has 85k on it, full tune up done 10k ago, plugs, wires, cap, rotor, fuel filter, pcv valve, air filter. O2 sensor is tested ok

 

Its def not compression cause my jeep has like 25 pounds in cylinder 4 and it runs like ****.Like a really bad skip/misfire lol it sucks

 

The O2 sensor can not work properly and still test OK and not throw codes. When a vehicle runs rich it is either high fuel pressure or the sensor. If it has 85,000 on it it is time for a change.

 

Renix = no codes
