Replaced the pesky leaky evap line that has been throwing the P0456 code for months. Hoping to get some driving done tomorrow and Wednesday so i can clear the code and get it inspected.

If you need it cleared, drop me a PM. My scanner should be able to clear the code.

Here is how the evaporative leak test is performed by the Power Train Computer:

When the leak test is performed, the vehicle must have been sitting for at least four to eight hours so that the engine temperature and outside air temperature are identical. There must also be between 15 and 85 percent fuel in the tank—this is to provide a baseline for the test since gasoline and diesel are volatile fluids that expand and vaporize easily with warm temperatures.
When the leak test initiates, the Vapor Canister Vent Valve is closed to prevent any fresh air from entering the EVAP system.
The Purge Valve is opened, which allows the engine to create a vacuum in the EVAP system.

After a specified time interval—usually about ten seconds—the Purge Valve is shut off and the vacuum level in the system is measured by the Fuel Tank Pressure Sensor.

Finally, a countdown initiates, which measures the rate at which the vacuum decays in the system. If the vacuum decays much faster than the specified rate or if no amount of vacuum is reached on two consecutive tests, then the Power Train Computer will fail the EVAP system for a gross leak and trigger the P0455 code.

Finished installing new stand alone transfercase shifter and changed seats and seatbelts in cherokee

Bought new (to me) seats from Bassman, and installed them. Haven't had a chance to take a ride yet, but they should be good. They sit a little higher, but not too bad.

Took my Jeep and dropped it off at Mid Rivers Chrysler Jeep. Totally done trying to fix this EVAP issue. Got a call like 45 minutes ago saying they think its the canister and it isn't covered under the federal emissions warranty or whatever. So I gave them permission to start work tomorrow on taking off the wheel and wheel well to get to the evap canister. For now I'm rollin' in a 5.0..I wish lol. My 3.5L Intrepid will do for now.
