OK, here's my delema, i recently bought and installed a new python injections ecu in my 90 HF. Well it works great and added incredible power, but lowered my idle to less than 500 rpm which is sooooooooo rough. I've had many freinds that know what they are doing look for my screw and there just isnt one. I've gotten many opinions, some say it must just be all controlled by the computer, and others say it has to have a screw. So i brought my question to you the all knowing honda pimps. Any help would be appreciated.
