    Thanks for the quick info and I do have to agree after looking back I was pretty vague,So here goes,The truck has 150,000 kms (93,362 miles),regular oil changes 5000 kms(3100 miles).Plugs changed this week along with the air filter,wires not applicable.The truck starts everyday,even in our cold Montreal winters,never stalls or hesitates plenty of pick up.Smooth idle.So all that tends to lead me away from Timing belt or fuel filter I may be wrong.The van is lady driven

    My wife uses it 95 percent of the time.She is steady driver.The CEL was on,but after changing the plugs (what a job) went out and hasn't come back on.Personally I am trying to read up on different sensors to see if one is faulty.And finally the verification was by cost and the onboard computer which says 19 liters per 100 kms (approx 12 mpg)

How are you verifying this? Are you going by an on-board fuel economy feature, or by actually buying twice the gas?
If you have verified the consumption the you may just need to tune it up; air/fuel filter, plugs, wires(if applicable) and a timing belt. (if applicable, you may have a chain) 07 is just old enough that you may have original plugs and filters. (don't know your mileage)

2007 Kia Sedona constantly emitting rotten egg smell

Its possible the problem is the cat, or it could be bad gas.
Have you tried switching to a different brand of fuel ?
And the cat may be covered by the dealer warranty.

I have a 2007 Kia Sedona. Occasionally it will have an overwhelming fuel smell both inside and ousted of the vehicle. A quick smell check leads me to believe that the issue is not engine related, as the...

My friends Carnival (Sedona) dose the same thing, This is just fuel vapor releasing from the breather. Nothing to worry about! If you want to keep up check's, keep a notice on how many miles you can do to a tank, if this reduces then you may have a leak. Have you local mechanic take a look

How much gas is left in the tank when the low fuel indicator light comes on in a 2007 Kia Sedona

Generally, vehicles have about 100 km of reserve left. Of course, this depends on how you drive it!

With that said, I have driven over 100 km in my 2004 Sedona, with the light on (and my knees knocking). Was in a place where fuel wasn't readily available and I went for it. I was happy to have the 5-5-5 warranty, as they would have come out with some fuel, ut it was a trying experience!

Hope this helps!!!
