OBD-1 PC based scanner
Can someone tell me where I can find information about OBD-1 scanners that
are suitable for 1993 Honda Del Sol/Civic cars . I am looking for FAQ/Howto docs. Thanks. A Del Sol Owner |

I was hoping for something more substantial, like hooking up the serial port of a PC, running some OBD tool, to a diagnostic port of the car and collecting performance data. I must be dreaming.:) I am specifically interested in learning about which cylinder is misfiring during engine idle. What other options do I have? There is no problem with CEL. |

Any advise on that would be appreciated. > yes you can, but it's massively expensive overkill and won't fix this problem. go to http://boomslang.us/ and read about their conversion kits if you want to do it the factory ecu way. getting back to your existing situation, check the ignition system and oxygen sensor. non-oem sensors are often abysmal and confuse the heck out of the ecu - don't use them. fresh ignition components help significantly too because the voltage needed to spark an idle mixture is greater than that needed to spark a running mixture. weak or failing insulation on the plug leads means it may run ok on the freeway, but give weak spark on idle. same for old plugs, worn distributor cap, etc. lastly, check the ignition timing. when doing it, [with the service connector on] check to see whether the timing marks are lashing back and forth. if they are, the timing belt could be loose - the ignition sensors run off the distributor which runs off the cam. loose belt means the whole timing for the vehicle is subject to "noise" and again, that affects smooth idle. correct valve lash helps too. |
