I have a 90 Si crx with a first gen b16a swap And I have searched and searched but can not find an answer. Like alot of honda's i have the retarded idle problem up down up down. i did a pressure test on the vaccum lines, no leak. I changed the IAC twice still didnt fix it and its throwing the code for iac still as well so i figure iac sensor is bad but When i unplug the sensor it changes and actually sounds better doing the idle bump in a range of 300 rpms when i plug it back in it goes back to the 2000 pm range so i figure the sensor is still good. next i check over the vacuum diagram and it looks way wrong from the 6 diagrams i saw and finally i went with the one that a majority of sites link to or say to use so i change the vacuum lines, reset the ecu, check coolant and once again it continues being gay. any help would be greatly appreciated

anyone???

 

well what happened to me was my map sensor had a slice in one of my wires, so i just soldered it, and everything was fine...

When you drive the car, does it bog out or feel very drastic power loss when u hit the gas? If so, id check the map sensor.. because that's what was happening to me..
