Last summer, I purchased a '99 Intrepid with 96K miles on it. On the advice of the previous owner (and the decal on the inside of the fuel door), I have consistenly avoided topping off the tank. Despite this precaution, it is consistenly susceptible to running rough and/or stalling when idling down, until I have gone through the first couple of gallons. Once in awhile, the Check Engine light will go on; when I had this checked by the shop, they said it was registering a "too rich" code.

Even after 100K mi. service (belts & plugs, mainly; I'll have to post details when I have the invoice in front of me), it's still doing it. Any possible remedy for this (short of siphoning out 2-3 gallons after filling, to be put back in later)?

Thanks!
