1988 audi 90 5cyl pinging

grewell912 · 05-03-2007, 02:10 PM

My 90 pings after riding on the highway and then coming to town with lower revs. It is only after I let off the gas and it is running down from say 2700 rpms. I even put 93 octane gas in it, and to no avail it still pings... any ideas!!??

This is a funny one coz mine does the same thing. Im guessing u mean like a spring noise, ive jus changed my clocks ie speedo and others and the noise has gon coz i was wondering wot it was. I initially thort it was my power band coming in but it was the clocks.. hope this helps...
