    I've got a 2004 3.4L Tacoma PreRunner Doublecab with a very sensitive gas pedal. All I have to do is gently press on the gas pedal and it will throw me back in my seat. Not too comfortable for the passengers either. It's been like this since I bought the truck new from the dealer but now my son is ready to learn to drive and I don't need the severe wipelash that may result.

    Does anyone know how to adjust the gas pedal so that it will require more foot pressure to accelerate and provide a smoother acceleration?

    Thanks, JDN

    Try a lighter foot? idk never heard of being able to change that out. try driving a 80's model suburban...it takes like 20 lbs of pressure to push that dang pedal

    My guess is that the twitchy behavior isn't caused by the accelerator pedal, but the throttle-by-wire system.

    Did you luck out and get a supercharger in the beastie when you bought it?

    Are you the original owner?

    If not ... There's actually a device on the market specifically designed to make throttle-by-wire systems more 'sensitive' to accelerator manipulation:

    I'm wondering if this (or some other such modification by a prior owner) might explain it ..

    ^interesting gadget but pricey!
    The accelerator sensor may be out of spec..manufacturing defect or maybe even corrosion etc. Maybe someone at a dealership with the plug-in tool can measure voltage for you to see if it is within specs. Possibly same with actuator for throttle body blade? I am assuming you've checked the return spring ( if there is one) on the pedal itself to see if it can be tightened for more resistance?

    An '04 would still be a throttle cable. Look at the throttle body, where the cable hooks up. There should be a little slack in it, when the throttle is closed. Perhaps yours is too tight? Maybe the cables got routed wrong durig some service work, or something?

    If its a cable system, it should also have a return spring, which is probably stretched, or has been inadvertently mounted incorrectly during service at some point. Look at all the linkages where the cable ends. Should be close to the end of the cable. Even if it's a throttle by wire system, it still has to have a return spring, in this case probably connected to the pedal. My bet is a weak/incorrect spring.

    Just for the record - the OP's 2004 V6 is throttle by wire, not cable-controlled. The electronic throttle control system for V6's arrived during the 2003 model year.
