Last week, while on a trip, my wife and I noticed a strong gas odor coming from our 2005 Pontiac Montana. The odor is inconsistent: sometimes we notice it when the van is running; other times there is no odor at all when running. Then, we may notice it when the van is parked (not running), but again at other times, there is no odor while parked. It does seem to be coming from under the hood rather than the gas tank. So I took it to a mechanic who had it for several hours and couldn't find any leak nor noticed any odor. He started and restarted the van and even drove it a couple times. Nothing. There was no odor for 2-3 days, but then today, it was back and stronger than ever. If we notice it while driving, we simply pull over, turn the van off and then back on, and it usually disappears. What do we tell the mechanic to look for?
