Audi S2 3B engine cold start problem.

Hello,

If engine is gold then rpm goes between 400-1000rpm. About a minute it will be steady.
What would be normal rpm with cold engine? Mines always been 800rpm. Cold or warm.
Also RPM-s will go crasy if i will stop before stop sine and then it will also do like it was gold engine. But after 20 minutes of ride, everything goes ok.
I today started car and it looks like only 3-4 cylinders work. revs jumped 300-1000rpm. After 10 minutes of ride and car was perfect again.

Remove ISV
Wash it out with paraffin or diesel
Lube with a little light oil
Re- install

See if that helps.

If it was ISV, then dosent it make trouble even if engine is hot?
