I didn't mess with the throttle body, but I did construct a new throttle cable hanger. See, my stock cable has so much slack it it, I would have to push the gas petal in half way before my truck would move, and as a result the throttle would only open a little more than half way. On my old Integra, there was a screw that I could use to adjust the tension on the cable, but since Ford engineers are cheap *******s, they just threw on some worthelss plastic clip. I machined a piece of aluminum and replaced the old hanger. Now the cable is extremely tight and 100 times more responsive and I've noticed a significant difference in acceleration with a fully open throtle. Let me know if anyone wants more information. -Kevin
the stock throttle body (and entire intake system flows enough air to supply a 302. the TB isn't the major choke point in our four bangers. you want to see it come alive get a port and polish paired with a more aggressive cam.
an EASIER way to take up the slack on the throttle cable is to go down to where the pedal meets the cable and pull the slack out and use zip ties to keep the cable from running back through the pedal
