I treated my 190E with powerboost foam. Now its playing up.
While I was treating it the revs stayed at 3000 rpm and didn't want to drop back down. I took it for a little 15 mile drive after letting it cool down for a half hour (was getting a bit warm) and now it idles at 1000 rpm, builds up to 1500, then drops back to 1000 in a constant loop. Any idea what it could be?
Incidentally, the inside of the intake manifold is now nice and clean where it was quite dirty before.
