Take it off clean it out with spray cleaner or such like and make sure you can hear the ball bearing rattle.

**matt_t5r** · Thursday 28th August 2014, 08:46

tried cleaning icv but still the same :-(

**claymore** · Thursday 28th August 2014, 08:49

I just unplug the icv, I run all my 850's with them disconnected.

**matt_t5r** · Thursday 28th August 2014, 10:00

does not make a difference if i disconnect it. actually idles slightly faster too.

Have you tried adjusting the throttle cable, it maybe too tight.

**MoleT-5R** · Thursday 28th August 2014, 10:15

Possible air leak in that case ??? or may be the throttle body needs a good clean, as it could be crudded up and not shutting fully, those would be my next suspects.

Air leak. simples

I had the same problem when I changed my engine, it was the seal between the master and the servo.

i had two maps for my 850r one held the revs and one dropped instantly when foot released, to be honest that made driving the car horrible very jerky on/off/on, its made/mapped for a smoother drive, if revs increase then an air leak is the cause i reckon

had this on mine it was the vac hose on the end on the inlet manifold by the thermostat right pain to get to but just get a length of vac pipe and run it round to the vac tree on the turbo intake pipe
