The most likely cause of your concern is a malfunctioning evaporative emission system. This system contains the raw fuel vapors and burns them in your engine when the computer opens a valve electronically. A clogged carcoal canister may be the culprit, but a professional that understands the system needs to give it a look.
Thanks, I changed the canister some time back but that didn't help.
