  2. Poor Idle/Shutter/CEL/Lights Flutter

    5th Gen
    I have a '99 Base.. I have a few issues. I am hoping they aren't issues at all. I just got the rear main changed, clutch replaced, and the serpentine done.. In the past week, I went to vtec and then had a flashing CEL... but it went off after 10 seconds, took my OBDII and no codes were found...
  3. Idle Surge

    3rd Gen
    Idle is surging between 1k and 1.6k. Cleaning the IAC valve didn't fix the problem. Blocking off the top port that goes to the IAC (inside the throttle body) makes the engine idle normally. The bottom FIT valve port (inside the throttle body) is sucking in air even when the engine is warm, and...

  10. Anyone, please help!

    3rd Gen
    So I have a 1988 Prelude, 5 spd. For some reason, it likes to idle real low, but I don't have an IACV or a MAF sensor, for I have a throttle body (carburetor). It occasionally, gradually picks up back to about 1400 rpm, but most of the time idles at about 100-150, maybe 200 rpm. I don't see any...
