Hey guys, new to the forum here. Just traded for a '95 Grand cherokee larado with 4.0. sometimes when im driving my spedo starts having seizures. One second im doing 100mp the very next im doing 5mph then after a few minutes it settles back down. any ideas?

 

they always called that a lead foot hahahahhahahaha


it probly is the speedo gear sensor

 

ya know i thought of the lead foot thing too but when i tied a dozen helium balloons to my foot they kept float up in my line of site lol. ty ill check the sensor see what i can figure out
