| OK, so I just bought a 92 Civic Si and the idle is really low looks like 200-300 RPM. I figured it would be the IACV since I know they go on Hondas. I pulled the IACV off my old Z6 that I have sitting around from my LSVTEC build. I also replaced the air filter, new plugs and wires. However, my idle is still low after the car has warmed up. car was bought from well almost 1 owner, 2nd guy owned for short time. it is completely stock! any suggestions would help out it is my DD. |

| there are no other problems except the low idle? No check engine lights, no problems driving the car? |

| correct, it hauls ass when driving just when sitting at light or warm temp, idle is low. I tried adjusting the TB screw the correct way with IACV sensor disconnected, then resetting ECU after adjusting to ~800RPM. no change no CEL |

| Im thinging the IAC may be bad, usually when the iac goes bad it gets stuck in the open position, causing the car to idle up and down but maybe yours is stuck in the closed position, if you have a donor IAC I would try swapping it out to see what happens, because if you followed the procedure and did everyhitng correctly (like you explained above) then you did all you can. The only thing I can tell is that Alldata says you should adjust the idle to 450 plus/minus 50rpm with No load, ill post the whole procedure

Adjust the idle speed by turning the adjusting screw on the throttle body.

| well I followed the steps from the super-honda site. I was thinking that it was the IACV also which is most typical vs. the FITV going bad. I swapped the IACV from my old Z6 did not solve problem. I cleaned and tested the FITV even swapped the thermo plunger from another donor FITV, this did not work either. I pulled the FITV again from my old Z6 and VWALLA! problem solved it was a bad FITV. IDLE is back to normal 750 RPM +/- Thanks for all the input! |

| OK new update. problem not solved! low idle again at lights it almost sputters a little, I already replace IACV from my old Z6 out of my EX that was running perfect. tach needle set just above 0 RPM only at a stop, if no gas and out gear while rolling idle is fine but within 30 seconds at the light idle gets real low. normal driving, no loss of power or hesitation at all! I changed plugs and wires as well as new air filter, everything on the car is bone stock, no mods. STUMPED! |
