Can the muffler system have something to do with your evap

What is your question?

Diagnostic say I have a large leak coming out of the charcoal canister the charcoal canister is fine so where the hoses around it can't seem to find out what the problem is I've already replaced the gas cap and the purge valve the only the other thing I know is my muffler is messed up and I want to know if it could cause problems and make the light come on

What makes this problem better or worse?

My car jumps at sometimes while you're sitting at a light or when you just idling

How long has your 2003 Suzuki Grand Vitara had this problem?

This problem has been going on for about a month
