Behind the spare tire. Weird place, but it's there.

Dude, looks like you're not getting it.
Describe your symptoms the best you can if you expect any help from the comedians on this forum.
As for canooter valve, as said before, they changed the design in 98 so your Jeep doesn't have one.....

 

Your tire temperature sensor could also be fouled up. Tends to produce the same symptoms.

 

True, the 98 and later models use a kantseeum valve.

 

Not so fast - my '98 has a canooter valve. They simply moved it underneath the Jeep, tucked up near the fuel tank.

OP: to test it, simply unplug the hoses. Make sure the ignition is OFF. Put a Mityvac on port 3, and apply suction. It should hold at least 15" of vacuum. With the ignition in the ON position, it should free-flow between ports 2 and 3. If it fails these tests, you can try replacing the O-rings, but many are corroded internally, and require a new one from the dealer. Avoid the Chinese replacements - they are a fire hazard.

 

The blue o rings will add about 3% horsepower if you install them on port 2.

 

OP, obviously these guys are a bunch of *******s. Try asking for help over at http://www.pirate4x4.com/forum/ Much friendlier group over there.

 

Way more friendly. They will even help pay for parts sometimes.

 

Yeah... Maybe one'll send ya' his spare canooter valve!

 

lol

 

My jeep is running a lot better with new injectors fuel pump PVC valve fuel lines

 

Any updates? I'm having the same exact problem. Not sure what it is or how to describe it but it sure seems like the problem the OP posted.
