Knock sensor fault...

[james22]

Hi people.

Yesterday afternoon, I had the Mrs AUII checked over for rego. While it was in there, I asked the guys to pull any error codes out of the computer.

Anyway, the car has been running horribly for quite a while now, Not starting in the morning when cold, running really rich, and lost a lot of get up and go.

I've been scratching my head over the cause for ages and it had me stumped. I'd tried replacing the 02 sensor, plugs, leads. Cleaned the T/body and ISC, reset the ecu, all to no avail.

So wasn't I pleasently suprised when the computer actually made my job easier for a change, by giving me an error code for the knock sensor.

Now what I wanted to know, is what the symptoms of a dud, or malfuctioning knock sensor are.
I know that its job is to retard the timing when the car starts pinging, but if it was faulty could it cause so many drama's with the car? Rich, lack of power, unco-operative starting etc

Cheers for your input people...
