The answer depends on whether or not you have any other prior criminal history, and any number of other factors.
Assuming that you have an offender score of "1" (that's counting your felony eluding charge as your only prior offense, and assuming that it hasn't "washed out" yet) you are looking at a standard sentencing range of 3-8 months.
But that's only a preliminary estimate based upon the truly sketchy details that you provided in your question. The true range could be more or less.
You should speak with an attorney right away, even if you haven't been charged yet, to get a more complete picture of what you are up against and what your options are.
