Hi!

I'm new to this forum, but not new to Hondas or Civics. Unfortunately I no longer own any of the 6 Civics/CRX's that I've owned, and gave away my manuals with them. (I currently own a 2001 S2000 while my wife drives a 2010 Fit-- we're Honda through and through).

My step-daughter has a 91 Civic LX that has died on her several times while driving. The symptoms, as described to me, are that the CEL comes on, and within about 10 seconds the car loses power and comes to a stop. By turning off the engine and restarting it, the car comes back to life.

More recently, this occurring more frequently and it is getting harder to restart when it does occur.

This morning, I went over to her house and pulled the carpet and saw that the LED in the ECU blinked once, paused, and then blinked 15 times.

From what I have read from searching, Code 1 is the Oxygen Content (with CATA)and Code 15 is Ignition Output signal.

Without a manual, I'm at a bit of a loss as to what to do next. But, my guess is that swapping the ignitor and/or coil would fix the problem with code 15.

My step-daughter's boyfriend said they tried to fix the problem by "gutting" the catalytic converter (figuring it would be easy to replace). So, I'm guessing that is responsible for the Code 1.

Am I on the right track? Any reason to try one before the other? Can I test either of them before replacing? Will fixing the ignition fix both codes?

Any other thoughts?

Thanks!!!

1 should be the o2 sensor which will cause it to run like crap and bog alot, not usually known for making it stall. 17 is for ignition output, which almost 9 outta 10 times is a break in the wire. I know that cel comes on at randowm for you cause my 89 hatch did the same thing. Its a black/yellow wire coming off the distributor you need to trace that and look for breaks or melted spots. Thats what is causing your car to stall out, and sometimes they will get to a no crank condition, and sometimes like how mine was it wouldnt affect anything hardly at all. Here is a useful link for future reference for obd0 cel codes.

also that is a single o2 system gutting the cat did nothing but make for more noise and emissions. If it was a bad coil you would most likely have a misfire constantly then. Id start with checking the blk/yel wire.
