1991 Toyota 3VZE RPM sudden drop and return at idle and when driving (Fix/Trick) DIY

My 1991 Toyota SR5 with the 3VZE motor will suddenly drop 500 RPM's and immediately return back to normal. This happens every couple miles and will jerk the truck as there is a sudden loss of power. In this video, I explain all the things I did and parts I replaced until I finally figured out the problem. I hope to help you diagnose the issue and solve the problem without buying parts that you don't need.
