1990 Audi 100, stutters, wheezes.

[Avinash Chopde]

Anyone have ideas on this - the dealer was stumped for 14 days
and even now the car is not working as well as it used to.

1990, Model 100, non-quattro, 200K miles.

Two weeks ago, it rained heavily, and after that, the
car would stutter when I hit the gas pedal - around 20MPH, it would
loose all power until I let off on the gas pedal.

The dealer replaced spark plugs, wires, distributor cap, and
then said it was fixed. They were wrong, that did nothing
to fix it (I had to pay for all that anyway :-).

Then after two weeks of trying a lot of stuff, they replaced
the air sensor potentiometer.

This fixed the problem to a large extent, now I don't have any
problem hitting the gas pedal. But when the car is driven a lot
or if it gets warm, the idle becomes extremely rough - sounds like
the car is wheezing - like a smoker with bad lungs???!!

Any ideas on what else to look for, mechanically the car still runs
fine, but the electronics seems to have the dealer stumped here.
He did say that the ECU seems ok.
