Hey, everyone. I have a question about my truck. It's a 2000 Ford 1/2 ton 4x4 with a standard tranny. It started jerking yesterday. It seems the faster I go, the less it jerks. Can anyone tell me what the cause of this is, and how I can fix it?

Thanks in advance!

 

Disregard. My engine light finally came on and Auto Zone was able to check my computer. Thanks anyway
