so my chech engine light is one once again. the code is PO455 which is EVAP leak. i have replaced my charcoal canister which was put on by BMW, and i bought a new gas cap, which was put on by me lol. so it has to be a vacum hose of some sort right?

and another thing, my car doesnt seem like it is driving right, im not getting any power out of it, it seems like, i have a short ram, exhaust, m50 and a shark injector so i should be feeling something but im not, doing you guys think the code is related to this problem or do you think there is another problem.

If it is a vacuum hose then it would explain your power lose depending on where the leak is.

ya, i sprayed carb cleaner around the visiable vacum hoses and i couldnt find the leak, its becoming a curse. i have recently realized it is even worse when my AC is on, i dont know if there is any relation

p0455 will not give you any symptoms other then very slight fuel economy loss.
