Ok I'm doing a my evap pressure valve and it doesn't seem to be cloged is there anyway I can unclog the canister with out buying a new one

 

i have tried but ended up ruining it! i just bought another one. trying to make sure you get any and all out of that little plunger area is a pita!

 

ususally if the evap canister is clogged it means that the charcoal pellets inside have all broken free and it will have to be replaced. if you leave it like that the engine is likeley to suck all the pellets through thre purge controll valve and into the intake. i have seen it happen a few times. luckily no damage to the motor but it cant be good for it.
