What's you opinion on an electronic throttle? How many other companies use this? I haven't really studied it, but off the top of my head the advantages seem to be eliminating the iac and the tps. However, with the sensor by the accelerator pedal, and the throttle blade being controlled electronically, it seems like another thing that can go wrong.

most modern cars for the last decade have used them... its nothing really new..
the primary performance advantage i see is throttlebody size.
you used to have to limit the size, because the throttle would otherwise be overly sensitive.
with the PCM controlling it, you can make the throttlebody oversize, then map out the TPS vs blade angle... allowing a nice even tip-in and good pedal feel... while still having a huge throttlebody for less WOT restriction.

I hate the electronic throttle in my trailblazer 4.2L. It just doesn't feel like my truck with a cable, or maybe its just me!

good system when working right.just think about this hung in wot.had a vortec fly by wire in shop that did.turned out to be bad pcm. most of tme pedal sensor is the only problem back then.left gm in 2000 to be a dodge tech.(bad move but pays better).
