Engine knock

["James M. De Arras" <jmd@westlab.com>]

My '88 80q has started to have an annoying knock at low rpm/idle.  This is
not lifter noise, I know the difference.  At 130k miles and 12 years, is
there a knock sensor that needs replacement?  Or any other ideas?

It's MUCH worse with lo-test gas, which I don't normally use, but ran out at
home, and that's all we had in gas cans for the lawn mower/generator.  But
it was knocking some before that.

 Any advice on what might be loose or what needs to be tuned to work right
 would be very help full...  I am going on a 450 mile trip and I would like

 Thanks a bunch!

Maybe a Tune-up including O2 sensor spark plugs and retiming might do the
car 
a little good.  You could also have a fuel component leaking such as an 
injector or a cold start valve.  You could have a bad thermal time switch or

maybe even a coolant temperature sensor.  All of these could affect the 
performance of your vehicle to that extent.  I am looking into the same 
problem on my GL5 and my 87 4000 quattro.
