Two codes

[LwnGy83]

I'm throwing two codes. One is the multiple missfire code, surprise, surprise, and the other is p1441. I know the second has to do w/ the evap system. I've looked at the gas cap and it's fine b/c it still hold pressure, I was wondering if the two codes could be related. The plugs are new, the wires are new and one coil is brand new and the other two are about a year old. I'm guessing I need to change the carbon canister, but I'm wondering if the missfires are being caused by the bad canister. I'm also thinking my EGR valve is going bad b/c I'm backfiring alot. Thanks for the help.

I had a similar P0441 code, and it took me about a year to find the cause. When I first got it scanned and wrote the codes down, I had P1441 and P0441. It seemed that they had the same thing in common. http://www.camarov6.com/ubb/ultimate...=011162#000000
There is a plastic hose that connects where the yellow arrow points here http://memimage.cardomain.net/member...0_230_full.jpg

The plastic hose broke and threw a code for the evap system.
