Speedometer going haywire.

Speedometer going haywire.
This saturday my speedometer on my 99 tacoma started going crazy on me. First it will drop and stay at 0, and then it will jump up to the correct speed then jump around a bit and drop back to 0. Sometimes it will give and hold the correct readings, but then it all goes crazy again. I bought the truck from a buddy back in 08 while I was in germany and am currently at Ft. Drum in upstate NY. This hasnt happened before and I will be honest I know very little about cars and trucks. Any help would be greatly appreciated. I need to get it fixxed soon as the current inspection runs out at the end of the month.

You have an electrical VSS (vehicle speed sensor) and my guess is there is a short in the wiring that is grounding out occasionally.
This is where the VSS is on the backside of the transfer case (assuming you are 4WD since you didn't give us any more information about your vehicle).
Read this thread, it will give you an idea of how to remove that part of the harness so you can check for bad wires.

Also, while your in there, pull the 2 screws that hold the VSS on and pull it off. Check the gears in there to see if they are chipped.

Sorry about that. Its a 2wd manual xmsn. No power windows or locks or any special frills not a 4wd. Like I said I know little to nothing about trucks and such haha. I like to tell people I know where the gas goes in and can figure out which hole the oil should go in :p I will check out what you suggested when I get home from work.

No, no you don't.
Enter the vin, find the "Speedometer driven gear" under powertrain/ chassis.

And it will give you the part number.

sometimes it is just the connector going into the sensor, same thing happened too me and it was a stick or something got up in the wires and pulled one back, caused a week connection
