First off any input on this thread will greatly be appreciated! My 2000 4.0 4x4 automatic has finally drove me to seek help! It starts up and runs fine as long as the abs/vss sensor on the rear end is unplugged. When the abs/vss sensor is plugged in it will get up to about 25mph or so and then the speedo will rapidly jump to over 90mph and the truck dies! It will start right back up but only to do the exact same thing. Already replaced abs/vss sensor and speedo cluster. Which made NO difference! Could the abs or pcm modules be causing this? Plan on having it scanned next week to see if any codes show up. There are no warning lights on or flashing on the instrument cluster. Also I'm guessing about the 25mph cause the speedo does not read correctly. Thanks again!
 
2000/2001 Rangers had an issue with the "thru body" connector under the drivers seat.

This may be caused by water intrusion at connector C309 (2000 model year) or C340 (2001 model year) under the driver's seat.
ACTION:

Inspect affected connectors; clean or replace connector pins as necessary. Install new sleeve and boot assembly over -14401- connector (interior). Refer to the following Service Procedure for details.

2000 vss issues

Well the through cab connection under seat was in good shape with no signs of rust or corrosion. It even still had a good amount of DE grease on all the pins. Going to try to get it to town today to have it scanned. Maybe something will show up. If not probably just keep shotgunning!
