1st off the sites traffic has slowed down considerably so responses will be slow if any.
2nd your grammar as well as a few of the others here is terrible, which makes thing hard to understand.
3rd as where I would love to help everyone here, I'm getting a little burned out on answering repair questions.
There are so many aspects of this forum that are not getting used, this is not a repair site & I'm not even sure we have any mechanics left on the forum. I'm not even sure if the Administrators even visit the site any more!
As to your questions have you noticed a leak, is the fuel smell heavy or light? It's natural for a light fuel smell. Remember your car will be 16 years old so check & replace things as needed (lines, filter, injector seals, pulsation damper).
Click the following link then read to get ideas on the idle problem. If you know nothing about repairs leave it to a mechanic.
I will check in from time to time, but not everyday
