I checked wiring and everything is O.K. (10 ohm). It means the idle ventil/solenoid has bad signal from ECU. Power suply to iddle controler is bad 4V (must be min 10V). Any advice. Any experience?

 

Check for pipe leaks, a BOV leaking will do the same if it's on the way out.

I have Blitz bov (1 year). I look on the piston and looks in close position. I will check pipes. (which?)

 

what year is it?

I've seen the idle valve on the 93-98 cars seize. if it's one of these take the top off the valve and make sure the shaft rotates.

If not, bit of light oil and tapping with hammer will free it up
