Re: Vibrations in A 92 Audi 100
Has your car ever exhibited pinging under mid-throttle position?
I have noticed it in my car - the pinging does not occur under full
load, only under light (mid) throttle application. Any ideas?

Don't know about the vibration thing, but I also suffered from the sharp
drops in RPM when I start off. Especially when shifting from 1st to 2nd,
which I basically deduced to be too rich fuel mixture as I need to stomp on
the gas to get it out of lug mode. I took it into Anderson-Behel Audi/VW
and they said the problem was due to a gummed throttle body. They also
found out that the Oxygen sensor wasn't working. The 5 year emission
warranty covered the O2 sensor and I paid $70 for the throttle body
service. All and all I'm happy as it fixed the problem!
