Jerks when accelerating

[75206]

Hello everyone,
I have a 99 4runner 100,000 miles, Runs great, until recently. During slow speeds acceleration is fine, but when you accelerate at high speeds, like when you are on the interstate and you step on the gas pedal, the truck jerks and hesitates. Where should I begin?
Thanks to all

Yeah, plugs and wires. It sounds like you might want to look over your manual and see what other scheduled maintenance it's do for, or go here:
