88 civic dx - erratic idle speed
Hi folks, my wifes 88 civic has this problem where the
idle speed will go too high all the time, kinda scary because it often happens when stopped like at a light or the drive-thru, which means you have to keep the brake pedal hard to keep from lunging forward. Often(but now always) it will trigger the check engine light, and if you turn the engine off and restart it will go back to normal..usually. Anyone else have or had this trouble? Any ideas apprecated, especially from any techs in the house. TIA |

Check the code. Turning off the engine will only clear the display on the dash, the ECU will keep the fault memorized until it's cleared by pulling a fuse (hazard) in the engine compartment. To get the code with the 88-91 Civics, lift the front of the carpet on the passengers side (there's a clip on the side that you may have to remove to be able to peek underneath). Under there is a nice metal box, with a fisheye window in the middle. Put your key in the ignition (not starting) and watch the little window - a red LED will morse-code out the flashes to you. It will keep repeating the code(s) over and over again. Say you have code 1 only, it will flash, pause, flash, pause... If you have code 1 and code 3, it'll do flash, pause, flashflashflash, pause, flash, pause, flashflashflash, pause... When you have the code(s) post back. I would bet one of them is code 1, Oxygen Sensor trouble. (just had mine replace in my 88 Civic LX) || Any ideas apprecated, especially from any techs || in the house.
