Re: [tech] knock sensor CisE... high idle... bad mileage... etc...

["Chris DeLong" <green536@hotmail.com>]

Check the vacuum line to the knock brain and test the throttle switches per 
Bentley. IF both of those check out then your knock brain could be bad. The 
little vacuum sensor on the brain will fail if it backfires out the intake 
in the right situation.


Can a bad knock sensor have anything to do with my 16V
idling too high once it is warmed up?  I noticed
pinging under heavy load and looked at the sensor
which has a cracked cover(never been off the block)
and the wire is totally deteriorated.  I'm also down
to 24mpg.  I just can't seem to get this beotch
running perfect anymore and haven't figured out why.
The 02 sensor is fairly new as well as plugs, cap and
rotor.  I haven't noticed any vacuum leaks either
although I haven't hooked up a guage yet(need to make
a connector). Any help/recommendations appreciated.  I
need to make connectors to test mixture also.... can
somebody make a tech article on this puhleeeeeze? :-)
