Revs dropping when lifting off

Check the idle switch on the tps is being triggered too

Audi PN 035919369M or Bosch Bosch 0280130037?

That's what I've bought, yeah

I'll be doing a bit of a sensor refresh along with the timing belt in a couple of weeks.

Certainly sounds similar to my issue. I should have said, I have a '91 3B.... does this sensor exist on my car? **Looks like it does and for the price of the one you linked on eBay I might as well switch it out.

After changing the ICV on my car it now idles well (well, okay) but ever since I've had it I've had a problem with the revs dropping to stalling levels when changing gear or just reving in neutral. I.E. When shifting from 2nd to 3rd gear I put the clutch down and the revs drops to an indicated 2-300rpm before it stabilised.

It sounds like an air leak to me, but has anyone experienced similar?
