[NESW20]

sounds like a poor design to me. the throttle pedal in my truck was 100% submerged in what might as well have been swamp water, and since then, my truck has done 120K miles without one single problem or hiccup.

as far as revving the engine, just have a friend do it from inside the car. instruct them what you want to do and that problem is solved.

you might want to do some more research before you insist that electronic throttles somehow add weight or cost. they eliminate the need for cruise control actuators and cables. they eliminate the need for idle air control valves. they eliminate the need for additional throttles to act as a power limiter for traction control systems (such as in the MKIV supras).

why do you think an electronic throttle is a specialized part for emissions? do they somehow let the air enter the engine differently than a mechanical throttle?
