has anyone swapped the stock throttle body
i was wandering if anyone has swapped the stock throttle body with a aftermarket one to get rid of the motor controlled throttle? and if so what kind did you use did you like it or was it a waste of time? just wandering since i know there problems with these throttle bodies.

Tom, I have wanted better throttle control as well. I disasembled a TB and the cable arm does not connect directly to the throttle blade. There is a roundish metal plate with a tab the will catch the thottle shaft at about 3/4 throttle. My thought was to make a nylon part that would basically directly connet the cable arm/shaft with the throttle shaft. Either that or weld a tab in the correct position to connect immediately. This would make it possible to apply force to the shaft. Unsure what the gearing and throttle motor control would do if this were the case. Worth an experiment. Unfortunately lost the TB in a move a few years back.

It's actually more than that. The automatic transmission won't work if you don't have the correct throttle body on the engine.
jbrady, a bunch of the guys over on the My.IS forums have done what you're talking about. They clock the APS(accel pedal sensor) housing so that little tab is forced to push on the throttle manually. It causes issues because the throttle motor wants to do certain things sometimes and it will fight your foot on the throttle. Yes it makes the engine response better, but it could also cause the throttle control motor to burn out prematurely.

i think so but who needs that i turn it off most of the time anyway and since i am in the process of changing it to a six speed i might have to look into this. i am in the process of rebuilding my throttle body right now just waiting on the throttle control motor. may be sell mine and get a bigger 90 mm throttle body anybody experiment with bigger throttle bodies? i have been thinking of doing a stand alone as well maybe building a mega squirt unit to run my motor.
