We purchased a used 1999 oldsmobile silhouette a few weeks ago, 132000 miles. (3.4 engine). 3 times I have received the check engine light on the instrument panel. Each of the times occurred after refueling a nearly empty tank (1/4 tank or less). The last time I tightened up the gas cap and the problem was solved but it has stayed on for the day this time. Also, right about the times that the light comes on the engine "hiccups', sometimes severely, and continues to do so until the light finally goes out. Any suggestions on what I need to check and/or how to fix and prevent this issue? Thanks!
