I recently took my wifes 07 in to Honda for a CEL which ended up being a misfire and a bad coil pack. Since we got the car back, anytime it sits for an extended time and we start it there is a faint gas smell inside the car. It only last for about a minute or so but something is obviously wrong as we never had this issue before. I'm assuming the fuel rail or an injector might've gotten bumped while they were swapping the coil packs and might be leaking slightly. Before I pull anything apart I was just curious if there is anything else that I should look for or check out?

TIA
