Hi Everyone: I am looking into going to Norway this Summer with some friends. We will be going to Norway, Finland & Sweden to do some kayaking & touring and then to Estonia, Latvia, & Lithuania to do some bike riding & touring. We have our choice of August or September travel.
The causes are varied and many. One thing is for certain. A horse that stumbles is a danger to the rider as well as to himself. Potential Reasons for Stumbling and Tripping (forelimbs) in Horses. 1  Long toes. 2  Tripping in the Forelimbs. 3  Hoof imbalances. 4  Laziness. Not balanced.  Green 1  Horse. Not fit/Poor muscle  tone.
Probable Causes: An engine that hesitates, stumbles or misfires when accelerating or when it is under load, is an engine that is either sucking too much air, not getting enough fuel, or misfiring. If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS).
