Fyi I just installed the accufab throttle body on my 04, and was definitely nervous from some of the things I've read. But doing some research on YouTube calmed me down. Found out all you need to do to control the idle, which I did have an issue with at first, is adjust the throttle position sensor.
What I did was remove the metal spacers that are in the spacer where the screws slide through, this gives enough space to adjust the sensor on the throttle.
So I am happy with the seemingly quicker response, no hanging revs just a usual idle, and the throttle body looks and feels to be of high quality. Just need to get an updated tune to go along with this.
Heres the link to the video that helped me quell my nerves on installing a throttle body on a 4V. I didnt have a voltage meter with me, was planning on having my brother use his if I couldn't get it working properly.
