This is not a good thing. I’ve chosen to use the Kilby EVAP Canister relocating kit that moves the canister up over the rearend, behind the gas tank. It also has a nifty skidplate (pictured here) that is nice, but if you hit the skidplate after relocating the canister, I suspect you’ll be having much bigger problems.
I’ve mentioned a couple of places in upcoming issues of the magazine that tearing off the EVAP canister puts the JK in limp mode, because that was what I was told by a friend at Jeep. I tried disconnecting the canister to see what would happen. Besides a trouble code and a light on the dash, the JK still ran. So, when you read my dire predictions regarding the loss of the canister in the magazine, disregard them. I wouldn’t permanently remove the thing, mind you, but it looks like if it gets torn off you’ll still be able to get home.
