my 190 16 valve has the strangest idle problem i have ever seen.

it follows no patter what so ever so im not even going to try to describe one.

but i can tell you that it idles as high as 2500 RPM or as low as 600. at 600 its almost dying.

most of the time it stumbles on the start up. like its missing a few ignitions. but after i give it some gas. it smooths out but then the above problem kicks it.

i replaced all the injector seals because they were old and dry and were letting air by. i checked my pouring water over the injectors. the engine coughed and spluttered.

but i am completely at a loss for the idle behavior of this car. and seeing as its supposed to be a highly tuned German racer. i embarrass my self when i drive it.
