Re: 164LS Check Engine Light

Karl,

For six months, I ignored this symptom as well since once I revved up the
engine, the "Check Engine" light went away.  One day, after a delightful
young female dance partner pointed it out while sitting at a stoplight, I
decided to fix it.  I can't have people think I'm ignoring my car (although
in this instance, I did).

So I pulled out the manual and tapped the gas pedal five times to wake up
the Motronic error codes.  What did I find?  "Intermittent Connectivity to
one of two knock sensors".  Hmmm.

So I went through the engine bay and found the two grey connectors to the
knock sensors.  I undid them and sprayed some connector cleaner in them,
followed by a good dose of compressed air, and plugged them back in.

This was a month ago and I haven't heard a peep from the Check Engine
light.  So it wasn't the O2 sensor that I originally thought.  Regardless,
that fixed it (so far).
