Aside from light flywheel, better spark plug wires, and grounding straps, what else can I do to improve throttle response.

 

Check cable and its routing for slop. Cable will slightly elongate as it gets old/fatigued.

 

Some other ideas:
- keep throttle cable and linkages clean and lubricated
- keep your fuel system (filter, injectors) clean
- maintain the rest of your ignition & electrical system (beyond plug wires & grounds)
- wear lighter, thinner soled shoes for driving

 

torque brace really really improves the driving feel

 

good suggestions. i was a little reluctant to try the torque bracing but i might give it a shot. btw, i do use very thin soled shoes. thanks for your time.

 

doc,
wow, taking the slop out really made a difference. my heal-and-toe-ing thanks you. i thought it was me!

 

I'm gonna check this on my car when I get home tonight. Thanks for the tip

 

How did you take the slop out ?

 

You should be able to adjust the nuts on the throttle cable in the engine compartment - the ones that hold the cable to the mount bracket. Adjust them to slightly move the end of the cable, and change tension or remove slack.

^yes, and it takes 2 minutes. it's not worth not doing.
also, is it better to tighten the nuts down again after the engine has completely cooled? if you tighten the nuts when it's hot, won't it loosen slightly when it's cold? or does it really matter? i know there are those rubber shims, are they to compensate for that?

 

Maybe even getting stiffer motor mounts, the urethanes I installed made a huge difference in throttle response.

 

The more expensive way to get a better throttle response is to get a free-flow exhaust, ported intakes, nice big K&N filter (more surface area = less air drag) Knife-edged butterfly, and a small resistor in-line with the intake temp sensor (1/5 of the resistance at room-temp in addition, should make it a tad better - but remove when you get an aftermarket ECU)

 

Adjusted the slop... there was a lot of it. Cant wait to take the car for a drive this weekend when I install new brake pads.
