    Has anyone had a trouble with the speedometer needle jumping from one reading to another? I noticed mine while using cruise and noticed the truck being jumpy like I was pusing the pedal quickly and releasing. I noticed the needle jumping when this was happening. I guess the speed sensor is faulty. Gonna get it worked on tommorrow.

    My speedo jumps around once in a while, but there is usually a corresponding wheel spin involved. I've heard of and experienced a "flare" in rpm's, but never heard of the speedo jumping around. I'd suggest getting it checked out. Good luck.
