High Revs On Idle?

[reno9 0]

My 205 1,9 dkz engined de-cat car is having too high revs on idle- its about 1500-2000 on idle with hot engine. I need to say that engine warning lamp is on sometimes and then its off again - but its not change the revs on idle. I already changed temp sensor but nothing - can it be dodgy lambda sensor? Fuel consumption is too little high about 12-13litres to 100km.

 

Any ideas??

first check SAD valve(automatic choke) and all breather pipe(leak) i think you mean K-light(diagnostic) if come on and of them car try to report failure.Try With diagnostic... if you dont have self diagnostic procedure for dkz(motronic) here is ... good luck

I checked the SAD (squeezed that hose and revs dropped a little bit) cant find any hose leaks too. When I first starts engine idle speed will be about 1100-1200rpm but after little run it drops to 1800-2000 and when I push trottle and let it back idle coms town and gets slowly back to 1800-2000rpm.

 

I tried that diagnostic but no results - led or diagnostic k-light not going to flash.
