Buggy Android accelerometer code

Hi all!

I need help regarding android accelerometers.

I am working on a bike game atm, and I have everything nice and setup, animation, physics, movement, etc. But there is one problem. I have the controls setup such that when you tilt your android device up or down, it moves forward, and left and right it turns. The problem lies in the turning mechanism. If I hold down the device at a corner for too long, it glitches out and stays stuck in that turning motion.

Here is the code for the control mechanism:

     public static float tiltThreshhold = .175f;
     public float moveSpeed = 4f;
     public float rotateSpeed = 3f;
     
     public static bool deadzone = false;
     
     
     private float panLimit = .9f;
     private float filter = 3f;
     public static Vector3 accel;
     
     public static float tiltCompare = .5f+accel.y;
     
     void Start () {
         accel = Input.acceleration;
         
     }
     
 
     
     // Update is called once per frame
     void Update () {
         Move();
     }
     
     void Move()
     {
             
             accel = Vector3.Lerp(accel,Input.acceleration,filter*Time.deltaTime);
             
             var accelerometerDir = new Vector3(0,0,.5f+accel.y*1.1f);
             
             var gravityDir = new Vector3(0,-5,0);
         
             var RotDir = new Vector3(0,accel.x,0);
             
             if(accelerometerDir.sqrMagnitude > 1) accelerometerDir.Normalize();
             
             transform.Translate(accelerometerDir*moveSpeed*Time.deltaTime);
             
         
             transform.Rotate(RotDir*rotateSpeed*Time.deltaTime);
             
             Debug.Log(accel.ToString());
         
     }

Please let me know asap! Also please let me know if I need to be more specific, or even show screenshots or video of what is going on. Thank you for your time

p.s. I am using unity 3.5 and due to financial reasons for licensing, wont be upgrading to unity 4 yet
