Q: why is my car idling erratically on 1996 Audi A4

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
To begin with, the engine never starts without heavy pedal assistance from me. When I stop revving the engine (when cold or hot) the rev counter flutters above and below 1000rpm with the engine struggling to settle. This repeats about 8 times before finally settling at a rock steady 850rpm.

any check engine light or fault codes? my first guess is a vacuum leak. check the vacuum elbow in front of the intake manifold i've seen them crack a few times. cleaning the throttle valve may help some. has the battery gone dead, been replaced or jumped recently? sometimes the throttle basic settings lock up and need to be reset (stored a throttle error code).
if you did replace the battery how would you reset the throttle basics- my engine light is on and it blinks 11-12 times
hi dont know if this will help but had the same problem with my 2.4 v6 a4 and i spoke to a freind whom told me to clean the throttle housing which on my car worked perfectly after it was cleaned but my rev counter fluttered all the time to the point where it would die but have had no problems since it has been cleaned its got to be worth a try at least
