I recently did this mod while cleaning my throttle body. Since I could see the throttle plate, I had my wife floor the pedal just to see how far it was opening up. To my surprise, it was only opening up about half-way! So, I took up the slack at the pedal with 2 zip ties and now it opens fully at full throttle and is much more responsive. I don't need to floor it anymore to merge onto the freeway. It is certainly worth checking out. It's easy to do and, while it won't turn your Ex into a tire shredder, the improvement will be noticeable if you have a lot slack in your throttle cable like I did.
